A particle starts from rest and moves with acceleration $a$ which varies with time $t$ as $a = k t$ , where $k$ is a constant. The displacement $s$ of the particle at time $t$ is:

Options:

Answer:

Solution:

$v = \int_{0}^{t} k t d t = \frac{k t ^{2}}{2}$ and $s = \int_{0}^{t} v d t = \frac{k t ^{3}}{6}$ . Option C.
