A body of mass m = 4 kg starts moving with velocity `v_(0)` in a straight line is such a way that on the body is being doen at the rate which is proportional to the square of velocity as given by `P = beta v^(2)` where `beta = ( 0.693)/( 2)`. Find the time elapsed in seconds before velocity of body is doubled.
