Ok, so this problem is kind of complicated, so ask me if you need clarification. This problem deals with Impulse and Momentum. There are two balls hanging vertically from a horizontal plane. Ball A is pulled back and is set up to strike ball B. Given for ball A - mass = 1.5 kg. Height = .3 m (measured from a horizontal plane from Ball B) initial speed = 5.00 m/s (as it leaves your hand) Given for Ball B - mass = 4.60 kg speed = 0 m/s (implied) Question a) is - Using the principle of conservation of mechanical energy, find the speed of Ball A just before impact. Question b) is - Assuming an elastic collision, find the velocities (magnitude and direction) of both balls just after the collision. I cant quite set up part A, I know I have to integrate a kinematics equation and the principle of conservation of mechanical energy, but I cant quite get it right. Thanks!!
