1.

A constant power P is applied on a particle of mass m. find kintic energy, velocity and displacement of particle as function of time t.

Answer» Correct Answer - B::C
(i) `W =Pt =1/2mv^(2)`
`(ii) v=sqrt(2pt)/m`
(iii) integrating the velocity, we will get displacement
`:. S=sqrt((2p)/(m))(t^(3//2)/(3//2)) =sqrt(8p)/(9m)t^(3//2)`.
