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.

Question

A 1.8-lb javelin DE impacts a 10-lb slender rod ABC with a horizontal velocity of v0 = 30 ft/s as shown. Knowing that the javelin becomes embedded into the end of the rod at point C and does not penetrate very far into it, determine immediately after the impact (a) the angular velocity of the rod ABC (b ) the components of the reaction at B. Assume the javelin and the rod move as a single rigid body after the impact.
