A force $F = B e^{- Ct}$ acts on a particle whose mass is $m$ and whose velocity is $0$ at $t = 0$ . Its terminal velocity is:

Options:

Answer:

Solution:

$m \frac{d v}{d t} = B e^{- Ct}$
; integrating from $0$ to $\infty$
$m v = \int_{0}^{\infty} B e^{- Ct} d t = \frac{B}{C}$
so the terminal velocity is
$v = \frac{B}{m C} .$
Option B.
