Two objects, P and Q, have the same momentum.Q can have more kinetic energy than P if it:
A)weighs more than P
B)is moving faster than P
C)weighs the same as P
D)is moving slower than P
E)is moving at the same speed as P

Question

Quizplus · Accepted Answer

Kinetic energy is directly proportional to the square of velocity. Therefore, if two objects have the same momentum but different kinetic energy, the one with the higher kinetic energy must have a higher velocity.
