The 15 lb suitcase is released from rest at C. After it slides down the smooth ramp, it strikes the 10 lb suitcase B, which is originally at rest. If the coefficient of restitution between the suitcase is e = 0.3 and the coefficient of kinetic friction between the floor DE and each suitcase if 0.4, determine a. Velocities of A and B just after the impact b. Distance B slides before coming to rest.

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.
