hope it helpslearn with brainlySuppose the airplane in the preceding problem fires a projectile horizontally in its direction of motion at a speed of 300 m/s relative to the plane. (a) How far in front of the release point does the projectile hit the ground? (b) What is its speed when it hits the ground?
Answer:
a) s = 5619.2 m
b) v = 456.5 m/s
Note: The preceding question is given below:
An airplane flying horizontally with a speed of 500 km/h at a height of 800 m drops a crate of supplies (see the following figure). If the parachute fails to open, how far in front of the release point does the crate hit the ground?
Explanation:
From the preceding question;
height, h = 800 m,
speed of plane = 500 km/h = 500000 m / 3600 s = 139 m/s
Speed of projectile = 139 m/s + 300 m/s = 439 m/s
a) using h = ut + 1/2 * gt² = 1/2 gt² (sice u = 0)
t = √(2h/g) where g = 9.8 m/s²
t = √(2 * 800/9.8)
t = 12. 8 s
horizontal distance, s = horizontal velocity * time
s = 439 * 12.8
s = 5619.2 m
b) Final vertical velocity v₂ = u - gt
v₂ = 0 - 9.8 * 12.8 = 125.4 m/s
horizontal velocity, vₓ = 439.0 m/s
resultant velocity, v = √(v₁² + vₓ²)
v = √{(125.4)² + (439.0)²}
v = 456.5 m/s

1. A mass of 630g is hung on a spring. Using Force = mass x gravity, what is the force of the mass, acting on the spring?
Answer:
The answer is 6.3
Explanation:
[tex]f \: = \: m(kg) \times g( \frac{n}{kg} )[/tex]
[tex]f \: = \: 630 \times {10}^{ - 3} \times 10 = 6.3[/tex]
The normal force acting on a body is the weight by gravitational pull of earth. The force acting on the hanging mass of 630 g is 6.17 N.
What is force?Force is an external agent acting on a body to deform it or to change it from the state of rest or motion. Force is a vector quantity having both magnitude and direction.
A normal force acting on a body is due to its weight by gravitational pull of earth. The force of gravitation is a kind of force by which an object attracts other objects into its centre of mass. The strength of force depends on the mass of the object.
The weight of an object in earth is the product of its mass and gravity. The acceleration due to gravity on earth is 9.8 m/s². Therefore, the force by weight of the hanging mass of 630 g or 0.630 Kg is :
0.63 × 9.8 m/s² = 6.17 N.

A disc is thrown through the air for 1.5 min with a power output of 12.5 W. How much work is done when throwing the disc?
Answer:
work = 1125 [J]
Explanation:
To solve this problem we must remember the definition of power, which is defined as the relationship between work and time. The power can be calculated using the following equation:
Power = work/time
Power = 12.5 [w]
work = joules [J]
time = 1.5 [min] = 90 [s]
work = 12.5*90
work = 1125 [J]

A battery provides a potential difference of 14V. What size current will flow through a 10 ohm resistor in this circuit?
Answer:
I = 1.4 [amp]
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.
Therefore:
V = I*R
where:
V = voltage = 14[V]
I = current [amp]
R = resistance = 10 [ohm]
I = 14/10
I = 1.4 [amp]
A loaded Costco shopping cart has a weight of 188 pounds(lb). You have to push the cart with a force of 14 pounds(lb) to keep it moving with a constant velocity of 1.1 m/s. What must be the magnitude (absolute value) of the force of friction on the cart?
Answer:
Force of friction = 14 pound
Explanation:
Magnitude = Force / Weight
Magnitude = 14 / 188
Magnitude = 0.074
So,
Force of friction = 14 pound
Force of friction is same as forcee
Frictional force along the direction of motion = 14 pounds
Frictional force is the resistance force towards relative motion. Frictional Force is a force the equation for which is given by the equation
[tex]f = \dfrac{\mu}{N} \\\mu = Coefficient \; of \; Friction \\\\N = Normal \; Reaction[/tex]
Weight of the Castco shopping cart = 188 Pounds (lb)
Force required to push the cart = 14 Pounds
Uniform velocity of shopping cart = 1.1 m/s
Acceleration in the direction of motion of cart = 0 m/s
So we can say that the forces in direction of motion must be balanced
So the magnitude (absolute value) of the frictional force along the direction of motion
= 14 pounds

The bike skids 41.5 m 41.5m41, point, 5, start text, m, end text with constant acceleration before it comes to a stop. What was the acceleration of the motorbike as it came to a stop?
Answer:
The acceleration of the motorbike as it came to a stop was -8.78 m/s² (NOTE: Negative sign indicates deceleration)
Explanation:
From the question,
A motorbike is traveling to the left with a speed of 27.0 m/s.
This is the initial speed, that is, initial speed = 27.0 m/s
Also, from the question,
The rider slams on the brakes and the bike skids 41.5 m, that is, the bike covers a distance of 41.5 m after the rider slams on the brakes.
Distance = 41.5 m
To determine the acceleration of the motorbike as it came to a stop,
Since, the bike came to a stop, then, the final speed is 0 m/s
From one of the equations of motion for linear motion
v² = u² + 2as
Where v is the final speed (velocity)
u is the initial speed (velocity)
a is the acceleration
and s is the distance
From the question
v = 0 m/s
u = 27.0 m/s
s = 41.5 m
Putting these into the equation
v² = u² + 2as
0² = 27.0² + (2×a×41.5)
0 = 729.0 + 83a
83a = -729.0
a = -729.0 / 83
a = -8.78 m/s² (NOTE: Negative sign indicates deceleration)

8.8 m/s^2
