Which of the following statements is the one that is true?
A)Momentum is a scalar quantity.
B)If the kinetic energy of an object does not change,its momentum can not change.
C)A spacecraft is traveling 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 a higher velocity.
D)The center of mass of an object must always lie within the object.
E)If two objects of different mass are subject to the same impulse,they will have the same change in momentum.

Question

Quizplus · Accepted Answer

Impulse is defined as the change in momentum of an object. When two objects are subjected to the same impulse, it means they experience the same change in momentum, regardless of their masses. This is a direct application of the impulse-momentum theorem, which states that the impulse on an object is equal to the change in its momentum.
