A 25 kg object and a 100 kg object collide. The graph below is for the 100 kg object. Assume momentum is conserved and find the impulse of the 25 kg object over the entire time shown.

A 160 g ball strikes a vertical wall and bounces off. The ball's initial velocity is a horizontal 5 m/s and the wall imparts an average normal force of 6.4 N for a time of 0.15 seconds during the bounce. What is the ball's final velocity (include magnitude and direction)? Use the impulse-momentum theorem to solve.

An estimated force vs. time curve for a baseball struck by a bat is shown in the figure below. (a) From the curve, determine the impulse delivered to the ball. (b) From the curve, determine the average force exerted on the ball.

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.

In tae-kwon-do, a hand is slammed down onto a target at a speed of 15.4 m/s and comes to a stop during the 4.29 ms collision. Assume that during the impact the hand is independent of the arm and has a mass of 0.770 kg. (the magnitude of the impulse is 11.9 kg*m/s)  What is the magnitude of the average force on the hand from the target? (PLEASE show how you get this answer )

A green pool ball (p = 30 kg x m/s) moves towards a yellow pool ball (p = -9 kg x m/s).  Then, the two pool balls collide.  After the collision, the green pool ball has a momentum of 3 kg x m/s.   How much momentum does the yellow pool ball have after the collision?  Explain your answer.

A car and a small truck traveling at right angles to one another with the same speed collide and stick together. The truck's mass is roughly twice the car's mass. Sketch the direction of their momentum vector immediately after the collision. Explain your result.

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?

Problem 3: An egg with a mass m is dropped from rest from a height h and falls to the ground and breaks. Part (a) Write an expression for the magnitude of the net impulse imparted to the egg as it is stopped by the floor. Your expression will be in terms of m, h, and g. Neglect air resistance. Expression : J = Select from the variables below to write your expression. Note that all variables may not be required. B, y, 0, b, c, d, e, g, h, j, k, m, n, P, S Part (b) What is the numeric value for the magnitude of the impulse if m = 0.045 kg and h = 1.6 m Numeric : A numeric value is expected and not an expression. J =
