A 1.0 kg cart travelling at 2.0 m/s [east] collides with a stationary cart, of mass 3.0 kg. The two carts stick together and move off at a constant velocity. Assume that friction is negligible. Consider a slightly different collision: same initial conditions, but after the collision the 1.0 kg mass instead has a final velocity of 1.0 m/s [west], and the 3.0 kg mass has a final velocity of 1.0 m/s [east]. Select the best statement below: Compared to the original collision, in Collision #2 Question 3 options: less total momentum was lost, but more kinetic energy was lost more total momentum was lost, but less kinetic energy was lost no momentum was lost, and no kinetic energy was lost no momentum was lost, but more kinetic energy was lost less total momentum was lost, but no kinetic energy was lost no momentum was lost, and less kinetic energy was lost
