- A trolley of mass 200 kg moves with a uniform speed of 36 km / h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other ( 10 m away) with a speed of 4 ms -1 relative to the trolley in a direction opposite to its motion and jumps out of the trolley. What is the final speed of the trolley
