When balls collide in a game of pool, the collision is almost perfectly elastic. Let us assume we have a perfectly elastic collision of two pool balls, one weighted heavier than the other, M1 = 0.175 kg and M2 = 0.250 kg. 1. Suppose the initial velocity of ball 1 is v1i = 1.2 m/s and the initial velocity of ball 2 is v2i = -0.5 m/s. Determine the initial momentum and kinetic energy. Show your work.

1. Suppose the initial velocity of ball 1 is v1i = 1.2 m/s and the initial velocity of ball 2 is v2i = -0.5 m/s. Determine the initial momentum and kinetic energy. Show your work.
2. Determine the final velocities of the two balls v1i and v2i after this elastic collision. Show your work.
3. If the collision took place in 1/20 of a second, t = 0.05 s, determine the average magnitude of the normal force acting between the balls during the collision. Show your work.
