Suppose that a ball decelerates from 8.0 m/s to a stop as it rolls up a hill, losing 10% of its kinetic
energy to friction. Determine how far vertically up the hill the ball reaches when it stops. Show your work.
The ball, shown on the above frictionless ramp, started from rest and slid down the incline with a constant acceleration of 4.5 m/s^2. How long would it take the ball to reach the .90 m (90 cm) mark? Show your work.
This question is a short free-response question. Show your
work for each part of the question.
15 m/s
100 m
An astronaut holds a rock 100 m above the surface of Planet
X. The rock is then thrown upward with a speed of 15 m/s,
as shown in the figure. The rock reaches the ground 10 s
after it is thrown. The atmosphere of Planet X has a
negligible effect on the rock when it is in free fall.
