Your work shown in an organized manner including: Show all work in you use for the first portion of the problem. Start with the basic physics relation you use in symbolic form. Your work should show the values you substituted in. (4 pts) Circle your answer this part (answer should agree with what you write in the box below. (2 pts) Show all work in you use for the second portion of the problem. Start with the basic physics relation you use in symbolic form. Your work should show the values you substituted in. (4 pts) Circle your answer this part (answer should agree with what you write in the box below). (2 pts) Puck one with M1 = 8M is moving on the ice as shown with speed v1 = 9vo. Puck two with M2 = 4M is moving on the ice as shown with speed v2 = 6vo. The sides of the two pucks are wrapped in Velcro, so that when the two pucks collide, they stick together. See the diagram below: Write your answers in the boxes below using the given symbols, for example: 6M vo^3. Your answers should not contain any symbols except M and vo. (A) After the two pucks collide and stick together, what is the x component of the velocity? [vx] (B) How much mechanical energy became thermal energy during the collision? [ETH]
