A body of mass m, accelerates uniformly from rest to `v_1` in time `t_1`. Find the instantaneous power delivered to the body as a function of time t.

Explanation

Acceleration , `a = (v_1)/(t_1)`
`:. ` Velocity , `(v) = 0 + at = (v_1)/(t_1) t`
`:.` Power , `P = "Force" xx "velocity" = mav`
or `P = m ((v_1)/(t_1)) xx ((v_1t)/(t_1)) = (mv_1^2t)/(t_1^2))`
