A ball is thrown with a 30 m/s horizontal velocity towards a vertical rod. The 2m rod is pinned at the top of the rod (point A) and it is free to rotate around this point. The ball contacts the rod 1.2m below A with a coefficient of restitution of .75. Assuming the rod has a mass of 10kg and the ball has a mass of .1kg, determine the velocity of the ball after impact.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
