A body of mass m accelerates uniformly from rest to

{v_1}

in time

{t_1}

. As a function of time t, the instantaneous power delivered to the body is

View answer and explanation

Correct option: D

\frac{{mv_1^2t}}{{t_1^2}}

Option D (

\frac{{mv_1^2t}}{{t_1^2}}

) is correct because the instantaneous power is calculated using

P = Fv

, where

F = ma

and

a = \frac{{v_1}}{{t_1}}

, leading to the given expression.

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
