Find the velocity of the lower stage after the explosion

Reference no: EM13534499

A two-stage rocket moves in space at a constant velocity of 4900 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1200 kg upper stage is 5700 m/s in the same direction as before the explosion. What is the velocity of the 2400 kg lower stage after the explosion?
