Two carts having masses 1.9 kg and 3.4 kg are on a frictionless track. The lighter cart traveling at 4.5 m/s collides with the heavier slower moving cart. The two carts latch together and continue rolling down the track with a velocity of 2.8 m/s. What was the initial velocity of the heavier cart? a. 1.9 m/s. b. 2.8 m/s. c. 5.3 m/s. d. 15 m/s. 11.
