A two-stage rocket moves in space at a constant velocity of +4970 m/. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1190-kg upper stage is +5990 m/s. What is the velocity
• (magnitude and direction) of the 2990-kg lower stage immediately after the explosion?
