consider a system of two carts. one cart, mass of 0.500 kg, is at rest. the other cart has the same mass, and is moving at 18 m/s to the left, towards the first cart. what is the total momentum of the system, before the collison?
Homework Answers
Total momentum of the system = momentum of first cart + momentum of second cart
One cart is at rest, so the momentum ( mass x velocity ) of the cart is zero.
Momentum of other cart = 0.500 kg x 18 m/s = 9.00 kg . m/s
Thus, the total momentum of the system is 0 + 9.00 kg . m/s = 9.00 kg . m/s

48) Two carts are moving towards one another at speeds of 2 m/s. Cart 1 has a mass of 1.5 kg and cart 2 has a mass of 0.5 kg. After the collision the 1.5-kg cart stops while the other cart moves back the way it came at some speed . Determine the final speed of the 0.5-kg cart and say whether this collision is elastic or inelastic . Represent this process with a sketch, an impulse-momentum bar chart, and...
