PhysicsEasysingle choice

A constant power delivering machine has towed a box, which was initially at rest, along a horizontal straight line. The distance moved by the box in time $t$ is proportional to :-

Options:

Answer:

Solution:

$P = C$ $\Rightarrow F V = C$ $\Rightarrow M \frac{d V}{d t} V = C$
$\Rightarrow \frac{V^{2}}{2} \propto t$
$\Rightarrow V \propto t^{1 / 2}$
$\Rightarrow \frac{d x}{d t} \propto t^{1 / 2}$
$\Rightarrow x \propto t^{3 / 2}$
