Solution for On-Line Homework 5 Inertia II Solution to On-Line Homework Problem 5.1(Concepts of Linear Momentum) Problem: Suppose you place two identical carts on an air track. Cart 1 you push so it is heading in the positive x direction with the an initial speed ( v 0 ). Cart 2 is at rest. After colliding elastically (no sticking together at all), what are the velocities of the two carts? Select One of the Following: (a-Answer) Cart 1 comes to rest, and Cart 2 heads in the positive x direction with speed v 0 . (b) Cart 1 bounces back at speed v 0 2 , and Cart 2 heads in the positive x direction with speed v 0 2 . (c) Cart 1 bounces back at speed

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...
