An 80-Mg railroad engine A coasting at 6.5 km/h strikes a 20-Mg flatcar C carrying a 30-Mg

Question:

An 80-Mg railroad engine A coasting at 6.5 km/h strikes a 20-Mg flatcar C carrying a 30-Mg load B which can slide along the floor of the flatcar (μk = 0.25). Knowing that the flatcar was at rest with its brakes released and that it automatically coupled with the engine upon impact, determine the velocity of the flatcar

(a) Immediately after impact,

(b) After the load has slid to a stop relative to the flat car.
