. Students place the end of a wooden board on some books so that the board can be used as an inclined plane. The
students release a ball at the top of the inclined plane and measure the time for the ball to reach the bottom
of the
ramp. The students perform three trials. The students then cover the board with a cloth and follow the same
procedure as before. The data are graphed below.
Part A
Describe two forces acting on the ball during the investigation
Current Attempt in Progress
A student (m = 58 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of
0.04 s. The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction.
From what height did the student fall? Assume that the only force acting on him during the collision is that due to the ground.

D In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 1.7 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it reached the teammate, assuming that the same force of kinetic friction acted on the puck everywhere between the two players?arrow_forward
