A rail way truck on a straight track is initially at rest. The truck is given a quick horizontal push by an engine so that it now rolls along the track. The engine is in contact with the truck for a time T=0.6sec and the initial speed of the truck after the push is 5.5m/s. The mass of the truck is 3100kg. Calculate the change in momentum(impulse), determine the maximum force exerted by the engine on the truck and when the speed of the second truck is 2.3m/s it collides with a stationary truck of mass of 4700kg. The two trucks move off together with a speed.Find it's final speed of the two trucks.
