Asked by Kathy

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

momentum is mass*velocity

momentumA=M/2*2V=MV
momentumB=MV

they have the same momentum
KE=1/2 m v^2
KEA=1/2 m/2*(2v)^2=mv^2
KEB=1/2 m *v^2=1/2 mv^2
