Homework Help: Physics

Posted by Anonymous on Wednesday, November 11, 2009 at 2:17pm.

A tennis ball of mass m = 0.065 kg and speed v = 25 m/s strikes a wall at a 45 angle and rebounds with the same speed at 45 (Fig. 7-29). What is the impulse given the wall?

I started out with finding the momentum and doubling it to get the impulse on the wall but that isn't the right answer. What equation do I need to start this one? Does it have to do with the angles they are giving me?
