On a frictionless, horizontal surface, a block of mass mm moving to the right at speed v collides with a block of mass my moving to the left at mi speed vi. A. Draw free body diagrams of both blocks at the moment they collide. B. When the blocks collide, how does Franz compare to Fur ma? C. How does the length of the collision for block 1 (fi) compare to the length of the collision for black 2 (t.)? D. Based on your arewers to (B) and (C), how does block I's change in momentum (Ap,] compare to block 2's change in momentum (Apa]? In AP Physics 1, momentum is In all collisions. This means that the total momentum of the two-object system must be the same both before and after the collision. In other words, any momentumn lost by the first object must be gained by the second object, Mathematically: E. A cue ball moving with momentum my collides with an at-rest 8-ball. a. What is the total momentum of the cue-8 system before the collision? b. What is the total momentum of the cue-8 system after the collision? C. If the cue ball stops as a result of the collision, then the 8-ball's momentum will be... d. If the cue ball's momenturn after the collision is 0.25my, then the B-ball's momentum will be... e. If the cue ball bounces backward with momentum -my, then the 8-ball's momenturn will be
