A 0.26-kg rock is thrown vertically upward from the top of a cliff that is 32 m high. When it hits the ground at the base of the cliff, the rock has a speed of 31 m/s. A) Assuming that air resistance can be ignored, find the initial speed of the rock. Express your answer using two significant figures. B) Find the greatest height of the rock as measured from the base of the cliff. Express your answer using two significant figures.

Cliff height. You are climbing in the high Sierra where you suddenly find yourself at the edge of a fog-shrouded cliff. To find the height of this cliff, you drop a rock from the top and 10 s later hear the sound of it hitting the ground at the foot of the cliff. Ignoring air resistance, how high is the cliff if the speed of the sound is 330 m/s?

A ball is released from rest from the twentieth floorfloor of a building. After 1 s1 s, the ball has fallen one floorfloor such that it is directly outside the nineteenth-floorfloor window. The floorsfloors are evenly spaced. Assume air resistance is negligible. What is the number of floorsfloors the ball would fall in 3s3s after it is released from the twentieth floorfloor?
Computation. A frictionless roller coaster cart is moving at 8.9 m/s when it is 31.7 m above the ground.
