A two-stage rocket moves in space at a constant velocity of $+4410\mathrm{m}/\mathrm{s}$. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the $1110?\mathrm{kg}$ upper stage is $+5830\mathrm{m}/\mathrm{s}$. What is the velocity (magnitude and direction) of the 2010-kg lower stage immediately after the explosion? Number Units
