A) A ball and bat, approach one another each with the same speed of 2.70 m/s, collide. Find the speed of the ball after the collision. (Assume the mass of the bat is much much larger than the mass of the ball and that this is an elastic collision with no rotational motion).
B) Find the factor by which the KE of the ball increases due to the collision.
