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?

A ball of mass 0.165 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.920 m. What impulse was given to the ball by the floor? kg-m/s

Kara Moore was applying make up in the parking lot. Unaware that Lisa's car was stopped in her lane 30 ft ahead. Kara rear ended Lisa's car. Kara's car was 1300 kg and was moving at 11 m/s and completely stopped after hitting Lisa's car in 0.14 sec. What is the net impulse experienced by Kara's car.

A golf ball m = 0.11 kg strikes a vertical concrete wall elastically with a horizontal velocity of v = 13 m/s.  Write an expression for the magnitude of the impulse I experienced by the ball. If the ball was in contact with the wall for t = .1s, what is the magnitude of the force F the ball experienced in N? If the ball rebounds with only half the velocity it comes in with, what is the magnitude of the impulse in kg m/s? Determine the magnitude of the change in kinetic energy in the above situation. Give your answer in joules.

A 0.280 kg volleyball approaches a player horizontally with a speed of 15.0 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.0 m/s. a) what impulse is delivered to the ball by the player? b) if the players fist is in contact with the ball for 0.600s, find the magnitude of the average force exerted on the players' fist.

Two rams are fighting and run straight at each other. Ram 1 has m1 = 115 kg and an initial velocity v1 = 9 m/s. Ram 2 has m2 = 127 kg and an initial velocity v2 = -7 m/s. When they collide, they lock horns.  What impulse did Ram 2 deliver to Ram 1?

A0.20 kg steel ball i dropped straight down onto a hard, horizontal floor and bounces straight up. The ball's speed just before and just after impact with the floor is 10.0 m/s. Determine the magnitude of the impulse delivered to the steel ball by the floor. O 4.0 N.s O 8.0 N.s O 12 N.s O 2.0 N.s O None of the given O 0.0 N.s

2. A ball of mass 0.26 kg is dropped from a height of 2.0 m. It hits the ground and rebounds to a height of 1.4 m.  a) What was the ball’s velocity and momentum immediately before hitting the ground? (b) What was the ball’s velocity and momentum just as it left the ground? (c) What was the impulse applied to the ball from hitting the ground? Take g = 9.81 m/s2 and show all your work

A 1390 - kg car moving at 6.00 m/s is initially traveling north along the positive direction of a y axis. After completing a 90° right-hand turn to the positive x direction in 5.00 s, the inattentive operator drives into a tree, which stops the car in 480 ms.
