A baseball player pitches a fastball toward home plate at a speed of 41.0 m/s. The batter swings, connects with the ball of mass 335 g, and hits it so that the ball leaves the bat with a speed of 37.0 m/s. Assume that the ball is moving horizontally just before and just after the collision with the bat. (a) What is the impulse delivered to the ball by the bat? Enter a positive value if the impulse is in the direction the bat pushes the ball and  enter a negative value if the impulse is in the opposite direction the bat pushes the ball. ____kg·m/s  (b) If the bat and ball are in contact for 3.00 ms, what is the magnitude of the average force exerted on the ball by the bat? ____kN
