Its quite simple. Now its given that it moves with constant acceleration.
That implies that it is under a constant force.
So F = constant.
Moreover, power = Fv (v = velocity at time t)
Also, v = u+at = at.
So, P = Fat.
But a = constant (acceleration is constant).
So, p = Kt=> P is proportional to the first power of t.
So A = 1.
