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.

A body of mass m, accelerates uniformly from rest to v_1 in time t_1.

1.	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.
Answer» <P> Solution :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))`
