alleryA heavy body and a light body have the same kinetic energy. The body with the greater momentum is:
Athe lighter one
Bthe heavier one
Cboth have equal momentum
Dcannot be determined
Answer & Solution
Correct answer: B. the heavier one
p = √(2mK); for fixed K, p ∝ √m, so heavier ⇒ larger momentum.
