A bat and ball approach one another each with the same speed of 1.50 m/s collides. Evaluate what is the speed of the ball after collision. (Suppose the mass of the bat is much larger than the mass of the ball and that this is an elastic collision with no rotational motion).
Compute the factor by which the KE of the ball increases due to the collision.
