Think whether it is an elastic, inelastic, perfectly inelastic collision? Justify? a. Cart 1 colliding with Cart 2 which is initially at rest (different masses) b. Cart 1 colliding with Cart 2 which is initially at rest and cart B has a much greater mass c. A collision between Cart 1 and Cart 2 where they stick together

complete the following 3 steps. 1. Indicate what your chosen system is (which objects are included in the system?) as well as your initial and final instants. Explain how your choice will help you solve the problem. 2. Draw a momentum-impulse bar chart for your chosen system that is consistent with the information given. 3. Write an equation using the bar chart as a guide and solve for any unknowns. A .06 kg tennis ball hits a wall with a velocity of 30 m/s and rebounds at about the same speed. What is the change in momentum of the ball from before the collision to after?

movement. 12. A small car meshes with a large truck in a head-on collision. Which of the following statements concerning the momentum during the collision are correct? * a. The momentum of the car-truck system is conserved, but the momentum of each one separately is not conserved. b. The momentum of the truck is conserved. c. The momentum of the truck and the car are each conserved. O d. The momentum of the car is conserved. O e. The car and truck must undergo the same change in speed. hp 7. 8

3. A 4 Kg of putty moving to the right has a head-on inelastic collision with 2 Kg putty moving to the left. If the combined blob does not move after the collision, what can we say about the speeds of the two blobs? a. V2 = V1 b. V2 = V1/2 c. V2 = 2*V1

You are playing lawn bowls. You roll one ball toward another of different mass that is initially at rest. They collide elastically and go off in different directions. (a) Choose values for the following. None of them can be 0.  i. The masses of the balls (they are different)               Ma= 2kg, Mb= 4kg  ii. The initial velocity of the ball you launch 6mls  iii. The angle at which the striking ball deflects after the collision 180 (b) Draw a photo before the collision, and another after. (c) Calculate the velocities of the two balls in x and y after the collision.
