Answer:
Work is defined as the amount of movement done by a force, and it can be calculated as:
W = f*d
where W is the work, f is the force and d is the distance.
So when the coach hits the ball, he is appliying some force in the ball (via the bat) that impulses the ball briefly (we can considerate that the force is only applied in a differential of time dt)
But we have a force applied and a displacement of the ball, so yes, the bat does work on the ball.
