Questions
A space craft of mass M is moving with velocity V and suddenly explodes into two pieces. A part of it of mass m becomes at rest, then the velocity of other part will be
a
MVM−m
b
MVM+m
c
mVM−m
d
(M+m)Vm
detailed solution
Correct option is A
After explosion m mass comes at rest and let Rest (M−m) mass moves with velocity v.By the law of conservation of momentum MV=(M−m)v⇒v=MV(M−m)Talk to our academic expert!
