AIPMT 2010 Mains | Work, Energy and Power Question 38 | Physics

A particle of mass M, starting from rest, undergoes uniform acceleration. If the speed acquired in time T is V, the power delivered to the particle is

$${{M{V^2}} \over T}$$

$${1 \over 2}{{M{V^2}} \over {{T^2}}}$$

$${{M{V^2}} \over {{T^2}}}$$

$${1 \over 2}{{M{V^2}} \over T}$$
