Question 1 of 5

Consider an equation of motion $m \frac{d^{2} y}{d t^{2}}+\gamma \frac{d y}{d t}-m g=0$ for a body of mass m moving with an initial velocity u. Find the change in the momentum of the body when it achieves a terminal velocity.

A

B

$m^{2}\left(g \gamma-\frac{u}{m}\right)$

C

$m\left(\frac{g}{\gamma}-u\right)$

D

$m^{2}\left(\frac{g}{\gamma}-\frac{u}{m}\right)$
