Question and answer
A 5,000 kg train is traveling at a velocity of 100 m/s and hits another train. the two trains stick together, and the new velocity is 50 m/s. what is the mass of the second train?
5,000 kg is the mass of the second train. Solution: (5000 kg)·(100 m/s) = 500,000 kg·m/s. ((5000+M) kg)·(50 m/s) = 500,000 kg·m/s (5000 +M) kg = 10,000 kg M kg = 5000 kg
