How long does it take an automobile traveling 66.7 km/h to become even with a car that is traveling in another lane at 52.7 km/h if the cars’ front bumpers are initially 119 m apart?
Answer:
30.6 seconds
Explanation:
Assuming the cars are moving in the same direction, the relative velocity is:
v = 66.7 km/h − 52.7 km/h
v = 14 km/h
Convert to m/s:
v = 14 km/h × (1000 m/km) × (1 hr / 3600 s)
v = 3.89 m/s
Distance = speed × time
119 m = (3.89 m/s) t
t = 30.6 s

What should not be used to support a scaffold because they could collapse, sending the structure to the ground?
Answer:
Cinder blocks
Explanation:
From safety training guides, whenever there is inadequate support, poor
construction, or a movement in the components of the scaffold such as the coupler as well as the base upon which the scaffold structure is built, there will be a great danger of collapse.
In light of this safety rule, Cinder blocks such as sandcrete blocks, bricks e.t.c shouldn't be used to support scaffold because they have a high tendency of being crushed under load

Part 1: Newton’s Laws Observe the virtual skateboarder coming down the hill and over the ramp. Describe how each of Newton’s laws of motion can be observed in this action. You can choose the dry, wet, or muddy conditions, or some combination of these. Newton’s First Law of Motion The skateboard riding down a hill with mud once the skateboard reaches the bottom it slows down due to frictional force acting in the opposite direction. Newton’s Second Law of Motion Newton’s Third Law of Motion
Answer:
the FIRST LAW NEWTON's skater goes down at a constant speed.
eaching the ramp in skidding, it has an acceleration due to the decrease in friction force. This is NEWTON'S SECOND LAW
NEWTON'S THIRD LAW, in the Normal force which is a reaction to the support of the skating
Explanation:
This problem asks to describe Newton's laws in a skater.
When going down a hill the skater acquires a constant speed, since the friction grows with the speed until it reaches the value of the weight component, In this case we see that the sum of the external forces is zero and According to the FIRST LAW NEWTON's skater goes down at a constant speed.
When reaching the ramp in skidding, it has an acceleration due to the decrease in friction force. This is NEWTON'S SECOND LAW
in this same part we can appreciate NEWTON'S THIRD LAW, in the Normal force which is a reaction to the support of the skating on the ramp and the planes the force of the skateboard on the ramp.
The force of friction of that stops the skateboard is equal to the product of mass and acceleration of the skateboard.
The skateboard riding down a hill with mud once the skateboard reaches the bottom it slows down due to frictional force acting in the opposite direction.
The force of the skateboard is equal in magnitude to the frictional force but in opposite direction.
Newton's first law of motion states an object at rest or uniform motion in s straight line will continue in that form unless acted upon by an external force.
The skateboard riding down a hill with mud once the skateboard reaches the bottom it slows down due to frictional force acting in the opposite direction.Newton's second law of motion states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The force of friction of that stops the skateboard is equal to the product of mass and acceleration of the skateboard.Newton's third law of motion states that for every action there is equal and opposite reaction.

A hiker moves across a mountain meadow that is 3 km wide in 40 minutes. What was her average velocity
Answer:
1.25m/s
Explanation:
Velocity is defined as the change of displacement with respect to time. Mathematically, velocity = displacement/time
Given displacement = 3km and time = 40minutes
Converting km to meters and minuetes to seconds;
Since 1 km = 1000m
3 km = (3*1000)m
3 km = 3000m
Also 1minute = 60seconds
40 minutes = 60*40 = 2400seconds
velocity = displacement/time
Velocity (in m/s) = 3000/2400
Velocity (in m/s) = 30/24
Velocity (in m/s) = 5/4
Velocity (in m/s) = 1.25m/s
Hence, the average velocity of he hiker is 1.25m/s

What can we say best describes the motion of the projectiles ? Assume air resistance is not a factor
Explanation:
A projectile motion may be defined as that form of a motion that is experienced by an object or a particle which is projected near the surface of the Earth and the particle moves along the curved path subjected to gravity force only.
Thus a projectile motion is always acted upon by a constant acceleration due to gravity in the down ward direction.
In the context, Quinn shoots two particle x and y from his sling shot and he observes that both his projectiles travels in a parabola curve in the air. Both the object x and y touches the ground a distance apart from him which is known as the range and it depends upon the velocity of the projectile. Both the projectile reaches a maximum height and then drop on the ground in a parabola shape.
B. The vertical velocity of projectile Y is changing, and the horizontal velocity of projectile X is constant.

What are the three equations of motion?There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
Keep in mind that these calculations only apply to uniform acceleration.
As given in the problem, we have to find the distance traveled when a donkey took 20 sec to fall from a cliff at 9.8 m/s2
initial velocity(u) = 0 m/s
acceleration(a) = 9.81 m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = ? ,u= 0 m/s , a= 9.81 m/s² and t =20 seconds
S= 0 + 0.5× 9.81×20²
S = 1962 meters
Thus, the distance traveled when a donkey took 20 sec to fall from a cliff at 9.8 m/s2 would be 1962 meters.

True or False: The height from which cliff divers jump affects the velocity at which they will fall. Velocity is speed in a certain direction. Include your reasoning with your answer.
Answer:
the diver's speed is independent of the launch height.
Explanation:
For this exercise we must use Newton's second law
fr - W = m a
the friction force has the general form
fr = b v
Let's analyze this equation to find out what happens with the speed of the distant club.
When jumping, the initial speed is zero, so the friction force is zero and has an acceleration equal to the acceleration of gravity, as the speed increases the friction force increases decreasing the acceleration until it becomes zero, when it arrives at this value the velocity it has is called terminal velocity and this velocity remains fixed in relation to the trajectory.
fr = W
v = cte
The distance or time in which this equilibrium is reached is relatively fast, so the diver's speed is independent of the launch height.
