Starting from rest, a basketball rolls from the top of a hill to the bottom, reaching a translational speed of 6.6m/s. Neglect frictional losses.
a) Evaluate the height of the hill?
b) Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. Find the translational speed of the frozen juice can when it reaches the bottom?
