A ball with a mass m is attached to the end of a string with a length 50.0 cm and is released from a horizontal position as shown in the diagram. At the bottom of its swing the ball strikes a block of mass M = 2m resting on a frictionless table. Assume that the collision is perfectly elastic. A) What are the velocities of the ball and block after impact. B) To what height does the ball rebound?(adsbygoogle = window.adsbygoogle || []).push({});

I didn't understand how to find the separate veolicties for each object, but i understood that the equation had something to do with the equation

mgh = 1/2mv^2

I found that solving out that equation got me 2.21 m/s for the total velocity, but i didn't know how to find the inidvidual velocities or how to find the height of the rebound, can I get some help please? Thanks
