Two objects of different mass have equal, non-zero kinetic energies. Which object has the greater magnitude momentum?
A) the lighter object
B) the heavier object
C) They both have the same magnitude momentum.

Question

Quizplus · Accepted Answer

Momentum is given by the formula p = mv, and kinetic energy is given by KE = 0.5mv^2. For two objects with the same kinetic energy, the object with the greater mass will have a greater momentum because it compensates for its lower velocity with its higher mass.
