a ball is kicked with an initial velocity of 11.0 m/s in the horizontal direction and 17.0 m/s in the vertical direction. (assume the ball is kicked from the ground.) (a) at what speed (in m/s) does the ball hit the ground?
Answer:
see below
Explanation:
maximum height attained= u²/2g
= 17²/2*10 m
= 14.45 m
speed on hitting the ground= √2gh
= √2*10*14.45 m/s
= 17m/s
hence it will hit the ground with same speed with which it was projected if we neglect the air resistance.
assume that 10 ft-lb of work is required to stretch a spring 4 ft beyond its natural length. what is the spring constant?
The spring constant is 2.5 ft-lb/ft.
What is spring constant ?Spring constant is a physical constant associated with a spring in a mechanical system. It is a measure of the stiffness of the spring, and is equal to the ratio of the force applied to the spring to the resulting displacement of the spring. The spring constant is usually denoted by the letter k. The unit of the spring constant is newtons per meter (N/m). In a linear system, the spring constant is a constant, and does not depend on the magnitude of the force applied or the displacement of the spring. The spring constant of a system is determined by the material properties of the spring and its geometry.
The spring constant, or stiffness, of a spring is defined as the amount of force (in units of force, such as pounds or Newtons) required to stretch the spring a certain amount (in units of distance, such as feet or meters).
Spring Constant = Work / Distance = 10 ft-lb / 4 ft = 2.5 ft-lb/ft.
Therefore, the spring constant is 2.5 ft-lb/ft.

- how much of the 100 kj of thermal energy at 650 k can be converted to useful work? assume the environment to be at 25oc.
Out of the 100 kJ of thermal energy at 650 K, only 53.9 kJ, or 53.9%, can be converted to useful work. The remaining energy will be rejected to the environment as waste heat.
To determine how much of the 100 kJ of thermal energy at 650 K can be converted to useful work, we need to calculate the maximum possible efficiency of a heat engine operating between these two temperatures.
The maximum possible efficiency of a heat engine operating between two temperatures T_hot and T_cold is given by:
efficiency = 1 - (T_cold / T_hot)
In this case, T_hot = 650 K and T_cold = 25 + 273 = 298 K. Substituting these values into the efficiency equation, we get:
efficiency = 1 - (298 / 650) = 0.539
Therefore, the maximum possible efficiency of a heat engine operating between these two temperatures is 0.539, or 53.9%.
To determine how much of the thermal energy can be converted to useful work, we can multiply the thermal energy by the maximum efficiency:
useful work = thermal energy x efficiency
useful work = 100 kJ x 0.539
useful work = 53.9 kJ

a child rides on a merry-go-round, traveling from location a to location d at a constant speed. what is the direction of the child's average velocity between a and d? take the origin to be the center of the merry-go-round.
The direction of the child's average velocity between locations A and D on the merry-go-round will be in the direction of the displacement of the child, which is the change in position from location A to location D.
If the child is traveling at a constant speed, the average velocity will be in the same direction as the actual velocity at any given moment. The actual velocity of the child is always tangent to the circular path of the merry-go-round, and so the average velocity will also be tangent to the circular path. This means that the direction of the average velocity will be perpendicular to the line connecting the origin (center of the merry-go-round) to the position of the child.
The direction of the average velocity depends on the direction of the child's movement along the circular path of the merry-go-round.

b) What is the ball’s centripetal acceleration?
The requried, a. average velocity = 9.42 meters/second and b. the ball's centripetal acceleration is 59.11 meters/second².
What is velocity?Velocity is defined as the rate of change in the position of an object with respect to time.
a) The average velocity of the ball can be found by dividing the total distance traveled by the time taken.
average velocity = total distance/time taken
average velocity = (3π meters/turn) x (120 turns/minute) x (1/60 minutes/second)

It is false to say that the viscosity of Newtonian fluids does not change with temperature.
A Newtonian fluid is one in which the local strain rate, or the rate of change of its deformation over time, is linearly connected to the viscous stresses resulting from its flow at every place. The rate at which the fluid's velocity vector changes determines how much stress is there.
The viscosity of Newtonian liquids is temperature-dependent, meaning that the viscosity reduces as the temperature rises. Generally speaking, the higher the viscosity, the faster the viscosity drops as the temperature rises.

The strain in the rope will be less than the weight of the box when I pull parallel to the hill while sliding a box up it at a consistent speed.
We can observe from the preceding figure that the sine component of weight balances the tension force. Additionally, because the box is travelling at a constant speed, the block experiences no acceleration, and as a result, there is no net force acting on the block. (The block is in static equilibrium, for example) The force balancing equation may be written as T - mgsin0 =0=T= mgsin0 (a) The amount of strain won't be more than it would be if the box were stationary because there isn't any friction present in this situation.

a comet has a perihelion distance of 0.79 a.u. and an orbital period of 54 years. to the nearest thousandth of an a.u., what is its aphelion distance from the sun
Aphelion distance from the sun when a comet has a perihelion distance of 0.79 a.u. and an orbital period of 54 years to the nearest thousandth of an a.u. is 3.13 * 2 = 6.26 astronomical units.
We may use Kepler's third rule of planetary motion, which stipulates that the square of a planet's orbital period (P) is proportional to the cube of its semi-major axis (a). It may be written mathematically as:
P^2 = a^3
where P represents the orbital period in years and a represents the semi-major axis in astronomical units. The semi-major axis is half the distance between the aphelion (the farthest point from the sun) and the perihelion (closest point to the sun).
Because the perihelion distance in this example is 0.79 astronomical units and the orbital period is 54 years, we can plug these numbers into the equation:
54^2 = a^3
a = (54^2)^(1/3)
When we compute the cubic root, we get:
3.13 a.u. = about 3.13 a.u.
The semi-major axis is around 3.13 astronomical units, and the aphelion distance is about 3.13 * 2 = 6.26 astronomical units.

ANSWER ASAP:
Two sound waves arrive at the same place at the same time and become amplified. Which type of wave behavior is exhibited?
A, Diffraction
B, Refraction
C,Reflection
D, Interference
The wave behavior exhibited will be diffraction. Then the correct option is A.
What is the Diffraction?Diffraction is the interfering or twisting of waves via an aperture into the area that is geometrically in the shadow of the obstruction or aperture. Effectively, the wave's secondary data collection is the diffracting element or aperture.
Diffraction is the technique by which a wavelength of light or other wave system is dispersed as a result of passing through a small aperture or across an edge. Usually, interference between the generated waveforms occurs in conjunction with diffraction.
Two sound waves arrive at the same place at the same time and become amplified.
The wave behavior exhibited will be diffraction.
Thus, the correct option is A.

The fact that we always see the same face of the moon tells us that the moon:________
The fact that we always see the same face of the moon tells us that the moon has synchronous rotation.
This means that the moon rotates on its axis at the same rate that it orbits the Earth, that the same side always faces us.
The reason for this is thought to be due to gravitational tidal forces from the Earth, which slowed down the moon's rotation and eventually caused it to become locked in this synchronous rotation.
As a result, the same side of the moon is always visible from the Earth, while the far side is hidden and only visible from spacecraft that have traveled to the moon. This has led to a wealth of scientific discoveries and a greater understanding of the moon's history and evolution.
