The space craft of mass M moves with velocity V in free space at first, then it explodes breaking into two pieces. If after explosion a piece of mass m comes to rest, the other piece of space craft will have a velocity -
A
MV/(M - m)
B
MV/(M + m)
C
mV/(M - m)
D
mV/(M + m)
Answer
MV/(M - m)
Explanation
Solution
MV = (M - m) u or u =
