Question

True False When a moving object explodes, its center of mass gains the energy of the explosion.
True False A space craft is travelling in space with its engines off. After a blast from the engines, the center of mass of the system (space craft + exhaust gases) continues with the same velocity.
True False If two objects of different mass are subject to the same impulse, the more massive one will gain less momentum.
True False Momentum is a vector quantity.
True False In an inelastic collision between two objects the velocity of the center of mass can change.

Explanation / Answer

1)False

2)True

1, 2 due to law of conservation of lenear momentum

3)False

as impulse is the change in momentum so if same impulse is given they will have same momentum

4)True

as momentum =m*v and v is a vector and m is scalar

5)False

due to law of conservation of lenear momentum
