Translational speed help!

A bowling ball encounters a h = 0.621 m vertical rise on the way back to the ball rack

Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 3.70 m/s at the bottom of the rise. Find the translational speed at the top.

I just need to know the formula for how to do this becasue i cant find it anywhere

Use conservation of energy. (Don't neglect rotational KE.)
