In a slow-pitch softball game, a 0.200-kg softball crosses the plate at 15.0 m/s at an angle of 45.0 %u030A below the horizontal. The batter hits the ball toward center field, giving it a velocity of 40.0 m/s at 30.0 %u030A above the horizontal.
(a) Determine the impulse delivered to the ball.
(b) If the force on the ball increases linearly for 4.00 ms, holds constant for 20.0 ms, and then decreases linearly to zero in another 4.00 ms, what is the maximum force on the ball?
