Part A. What is the magnitude of the impulse delivered by the bat to the ball? Part B. If the bat is in contact with the ball for 1.5 ms, what is the magnitude of the average force exerted by the bat on the ball?

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 car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 5.40 m/s in 0.882 s. What is the magnitude of the linear impulse experienced by a 72.0-kg passenger in the car during the time the car accelerates? What is the magnitude of the average total force experienced by a 72.0-kg passenger in the car during the time the car accelerates?

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.

A fan blows a cart of mass m a distance d. The same fan blows a heavier cart of mass 2m through the same distance d.  Which cart experiences the larger impulse? Options: A) The lighter cart experiences the larger impulse. B) Both carts experience the same impulse. C) The heavier cart experiences the larger impulse. D) The answer cannot be determined.

A very elastic rubber ball is dropped from a certain height and hits the floor with a downward speed v. Since it is so elastic, the ball bounces back with the same speed v going upward. Which of the following statement about the bounce are correct? There could be more than one correct choice. A.) The ball had the same momentum just before and just after the bounce. B.) The magnitude of the ball's momentum was the same just before and just after the bounce. C.) The ball's momentum was conserved during the bounce. D.) None of the above statements are correct.

A golf ball of mass 0.045 kg is hit off the tee at a speed of 35 m/s. The golf club was in contact with the ball for 3.50×10−3 s. Part A Find the impulse imparted to the golf ball.
