A red train traveling at 72 km/h and a green train traveling at 144 km/h are...

A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other along a straight, level track. When they are 840 m apart, each engineer sees the other's train and applies the brakes. The brakes slow each train at the rate of 1.0 m/s2. Is there a collision? If so, give (a) the speed of the red train, (b) the speed of the green train, and (c) the separation between the trains...

A train, A, with a mass of 19,000 kg is travelling at 90 km/h when it strikes a second train, B, which has a mass of 17,000 kg and is moving in the same direction at a speed of 43.2 km/h. If the coefficient of restitution for the collision is 0.87 and all resistances to motion are negligible, then (i) calculate the speed of the trains A and B immediately after the impact. (ii) as a result of damage during...
