Calculate the work done by the baseball bat on the baseball for the second player (who hits the fast line drive). Report your answer as a positive number for positive work done on the ball or a negative number for negative work done on the ball.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
