Complete the sentences below correctly. stunt car a and stunt car b are identical cars with the same mass of 48.9 kg. they are both traveling at 82.5 m/s. stunt car a crashes into a brick wall, while stunt car b crashes into a big pile of leaves. they both come to a complete stop after the impact. stunt car a experiences a over a of time. stunt car b experiences a over a of time. because of the force experienced by stunt car a, it will sustain damage than stunt car b.

the possible answers are: short period, large force, more, long period, small force, less.

Stunt Car A experiences a large force over a short period of time. Stunt Car B experiences a small force over a long period of time. Because of the force experienced by Stunt Car A, it will sustain more damage than Stunt Car B.

Explanation:

Both cars have the same mass and velocity, therefore they have the same momentum. During the collision, the total momentum of the car A and brick wall is conserved as well as the total momentum of the car B and the pile of leaves.

However, if we are to investigate the damage on each car, we should look at the cars not the whole system. So, the momentum difference between the cars gives us the impulse that the car felt.

Since the Car A will crash the wall quicker than the other car crashes through the pile of leaves,

which gives us

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
