Current Attempt in Progress

Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of $5\mathrm{.}2\frac{m}{s}.$ Ignore frictional losses. $($a$)$ What is 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. What is the translational speed of the frozen juice can when it reaches the bottom?
