Product description
A car of mass m1 = 10 t with an automatic coupling, moving at a speed v1 = 12 m/s, catches up with the same car of mass m2 = 20 t, moving at a speed v2 = 6 m/s, and couples with it. Moving further together, both cars collide with a third car of mass m3 = 7.5 tons standing on the rails. Find the speed of movement of the cars on different sections of the track. Ignore friction.
