Homework Help: Physics

Posted by CJ on Wednesday, March 21, 2007 at 11:34am.

A bowling ball encounters a 0.76m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. If the translational speed of the ball is 3.80m/s at the bottom of the rise, find the translational speed at the top.

Take the initial KEnergy, subtract the graviatational potential energy on the rise, and the remainder is KE. From that, compute speed.
