A space craft of mass M is travelling in space with velocity v. It then breaks up into two parts such that the smaller part m comes to the rest, then the velocity of the remaining part is-

A body is moving with a velocity v , breaks up into two equal parts. One of the part retraces back with velocity v . Then the velocity of the other part is

A space- craft of mass 100 kg breaks into two, when its velocity is 10^(4)ms^(-1) After the break a mass of 10 kg of the space craft is left stationary the velocity of the remaining part is:

A body of mass M moves in outer space with vleocity v. It is desired to break the body into two parts so that the mass of one part is one-tenth of the total mass. After the explosion, the heavier part comes to rest whole the lighter part continues to move in the original direction of motion. The velocity of the small part will be

One projectile moving with velocity v in space gets burst into 2 parts of masses in the ratio of 1:2. The smaller part becomes stationary, the velocity of other part is
