Question

When two bodies with different masses have the same momentum. a) have equal kinetic energies b) the body with the greater mass has greater kinetic energy. c) the body with the largest mass has less kinetic energy.choose the correct answer 

Answer 1

The momentum of an object is the product between mass and velocity, if the two bodies have different masses but same momentum, it means they have different velocity, the body with greater mass has greater velocity, hence, it has greater kinetic energy because this energy depends directly on the velocity.

Therefore, the answer is B.
