Explanation:
momentum (p) = mass × velocity.
Change in momentum (∆p) = final momentum - initial momentum.
∆p = 0.045×38 - 0.045×0
∆p = 1.7 kg m/s.

According to Second Newton's Law, a force is defined as
That is, a force accelerates the mass which is being applied such force. So, in this case, we have to replace given values, and find![F](/tpl/images/0049/8113/890c7.png)
Therefore, the right answer is the second option.
