1. The problem statement, all variables and given/known data Set the cars so the spring mechanism is touching a side if a cart without a spring mechanism. When you it the spring the carts should move in opposite directions. Based on the results, disregarding error, momentum is conserved. What are some everyday practical applications of this lab? 2. Relevant equations (m_1 〖∆x〗_1)/(m_2 〖∆x〗_2 ) 3. The attempt at a solution I thought about cars because they bounce of each other but they don't start together. Another idea I had was a diver on a diving board.
