Question

Starting from rest, a basketball rolls from the top of a hill tothe bottom, reaching a translational speed of 5.44 m/s. Ignore frictional losses. (a) What is the height of the hill?
1 ______ m

(b) Released from rest at the same height, a can of frozen juicerolls to the bottom of the same hill. What is the translationalspeed of the frozen juice can when it reaches the bottom?
2 _______ m/s (a) What is the height of the hill?
1 ______ m

(b) Released from rest at the same height, a can of frozen juicerolls to the bottom of the same hill. What is the translationalspeed of the frozen juice can when it reaches the bottom?
2 _______ m/s

Explanation / Answer

    m g h = (1 / 2) m v2     v = (2 g h)       solve for the height of the hill h     in the similar manner knowing the mass of thefrozen juice calculate the speed of the frozen juice
