Question

A body of mass `m` is acceleratad uniformaly from rest to a speed `v` in a time `T` . The instanseous power delivered to the body as a function of time is given by
A. `(V)/(T) t`
B. `(V^(2))/(T) t^(2)`
C. `(V^(2))/(T^(2)) t`
D. `(V^(2))/(T^(2)) t^(2)`

Answer 1

Correct Answer - C
Power `= ("work done")/(time) = (V^(2) t^(2))/(T^(2) t)`
Power prop `(V^(2) t)/(T^(2)`.
