Answer 1

Answer:

We know

Power = Force . velocity

Force is constant I.e. acceleration is constant .

$so \: \: a = \: const \\ v = \int \: adt = at + c$

Or linearly dependent on time.

So

$p = f(at + c) \\ p = ma(at + c)$

Note that m , a and c are constants .

So relation between p and t is linear

.

At t = 0 , P = 0

So we get c = 0

So $P = ma^2t$

So answer is option b
