Question
Two billiard balls with the same mass m move towards one another. Ball one moves in the positive x-direction with a speed of v1i = 2.8 m/s and ball two moves in the negative x-direction with a speed of v2i = 1.84 m/s. The two balls collide elastically, and both balls change direction after the collision. Write an expression for the horizontal of the system's initial momentum p(i) in terms of m, v(li), and v(2i+) and then the final momentum p(f) in terms of m and the final speeds of the ball one and ball two v(2f)
Explanation / Answer
intial =final momentum = 0.96 *m
