A batter hits a foul ball. The not-so-fast 0.140-kg baseball that was approaching him horizontally leaves the bat at 30.0 m/s in the opposite direction, causing the ball's initial kinetic energy (i.e. the ball's kinetic energy before it was struck with the bat) to increase by 125%. What is the magnitude of the impulse delivered to the baseball?

    A batter swings at a baseball (mass 0.145 kg) that is moving horizontally toward him at a speed of 40.0 m/s. He hits a line drive with the ball moving away from him horizontally at 50.0 m/s just after it leaves the bat. Part A If the bat and ball are in contact for 8.00 ms, what is the average force that the bat applies to the ball? Express your answer with the appropriate units.
