In a softball game, a 0.2kg ball crosses the plate at 10 m/s at an angle of 45° on its way down. The batter hits the ball toward center field, giving it a velocity of 45 m/s at 30° above the horizontal. a. Determine the impulse given to the ball. b. If the force on the ball increases linearly for 4 ms, holds constant for 20 ms, and then decreases to zero linearly in another 4 ms. i) What is the average force on the ball? ii) What is the peak force on the ball?

Question

Transcribed Image Text:In a softball game, a 0.2 kg ball crosses the plate at 10 m/s at an angle of 45° on its way
down. The batter hits the ball toward center field, giving it a velocity of 45 m/s at 30°
above the horizontal.
a. Determine the impulse given to the ball.
b. If the force on the ball increases linearly for 4 ms, holds constant for 20 ms, and then
decreases to zero linearly in another 4 ms.
