A 0.500-kg ball is dropped from rest at a point 1.10 m above the floor. The ball rebounds straight upward to a height of 0.480 m. Taking the negative direction to be downward, what is the impulse of the net force applied to the ball during the collision with the floor?

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.

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?

A 0.350 kg lump of clay is dropped from a height of 1.15 monto the floor. It sticks to the floor and does not bounce.   What is the magnitude of the impulse ? imparted to the clay by the floor during the impact? Assume that the acceleration due to gravity is ?=9.81 m/s2. The force exerted by the floor on the clay is plotted as a function of time in the figure. What must have been the maximum force ?max exerted by the floor on the clay?

A rubber ball of mass 29.5 g is dropped from a height of 1.95 m onto a floor. The velocity of the ball is reversed by the collision with the floor, and the ball rebounds to a height of 1.55 m. What impulse was applied to the ball during the collision?

In tae-kwon-do, a hand is slammed down onto a target at a speed of 13.2 m/s and comes to a stop during the 5.16 ms collision. Assume that during the impact the hand is independent of the arm and has a mass of 0.654 kg.What is the magnitude of the impulse?8.63 N*s What is the magnitude of the average force on the hand from the target? (Answer 2nd question)

In walking the body goes through both a breaking impulse and a propulsion impulse. The breaking phase lasts .3 seconds and the propulsion phase lasts .33 seconds. The body goes through a decrease of the vertical velocity of .1 m/s as they come into the ground during the breaking impulse and an increase in the vertical velocity of .4 m/s during the propulsion.  The individual has a weight of 700 newtons. What is the acceleration horizontally for both the breaking impulse and the propulsive impulse if the coefficient of friction is .32?

A rubber ball of mass 30.0 g is dropped from a height of 2.00 m onto a floor. The velocity of the ball is reversed by the collision with the floor, and the ball rebounds to a height of 1.50 m. What impulse was applied to the ball during the collision?

A 0.12-kg ball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. What is the magnitude of the linear impulse experienced by the ball?
