Ball B.
Momentum = m*V.
Ek = 0.5m*V^2.
Ball A:
Momentum = (m/2)*2V = m*V.
Ek = 0.5m*V^2
a. Their momentum is equal.
b. Their kinetic energy is equal.
Please, help me answer this question.
Two balls are moving in the same direction. Ball A has half the mass of ball B, and is moving at twice its speed.
(a) Which ball has the greater momentum?
(b) Which ball has greater kinetic energy?
Thank you.
