Unformatted text preview: v , and Cart 2 heads in the positive x direction with speed v . (d) Cart 1 bounces back at speed v , and Cart 2 remains at rest. Solution Velocity is interchanged. Thus, Cart 1 will now have ve-locity and Cart 2 will have velocity + v . This is the only possible combination of those given that will conserve momentum. When we learn about types of collisions and energy considerations, we will know how to prove this is the only possible solution for an elastic collision. 1 Total Points for Problem: 2 Points 2...
