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.

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. In a game of billiards, ball A is given an initial velocity vo along the longitudinal axis of the table. It hits ball B and then ball C, which are both at rest. Balls A and Care observed to hit the sides of the table squarely at A'and C', respectively, and ball B is observed to hit the side obliquely at B! It is given that vo = 6 m/s, VA = 1.92 m/s and a = 1.65 m. 0.75 m 0.75 m A 1.8 m B' 1.2 m C' Determine the Point C'where ball Chits the side of the table. Assume frictionless surfaces and perfectly elastic impacts (that is, conservation of energy). The Point C'where ball Chits the side of the table is .51 * m.
