A ball and bat, approaching one another each with the same speed of 1.1 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).
For the previous problem, find the factor by which the kinetic energy of the ball increases due to the collision.
