Atwo-stage rocket moves in space at a constant velocity of +4300 m/s. the two stages are then separated by a small explosive charge placed between them. immediately after the explosion the velocity of the 1160-kg upper stage is +5940 m/s. what is the velocity (magnitude and direction) of the 2100-kg lower stage immediately after the explosion?
