Apitcher throws a 0.200 kg ball so that its speed is 19.0 m/s and angle is 40.0° below the horizontal when a player bats the ball directly toward the pitcher with velocity 46.0 m/s at 30.0° above the horizontal. assume +î to be along the line from the batter to the pitcher and +ĵ to be the upward vertical direction. (express your answers in vector form.) (a) determine the impulse (in n · s) 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 (in n) on the ball?
