Question

Which of the following has greater momentum?
a. An object of mass 2 kg moving with uniform velocity of 2 m s${}^{-1}$.
b. An object of 1kg mass moving with uniform velocity of 3 m s${}^{-1}$.

Answer 1

a. momentum, p = m $\times$ v

= 2 $\times$ 2 = 4kgm/s

b. momentum, p = 1 $\times$ 3 = 3kgm/s

a has more momentum as compared to b.
