Power supplied to a particle of mass 2 kg varies withtime as P =(3t^2)/2W,where t is in seconds. If velocity of particle at t=0 is zero, then the velocity of particle at t=2 s will be |

Answer» 1 m `s^(-1)` `therefore K_f-K_i = INT P DT` `rArr 1/2 mv^2-0 = int_0^2 (3/2t^2) dt rArr1/2(2) v^2=3/2 [t^3/3]_0^2 =4` `therefore` Velocity of the particle at t=2 s will be , v=2 m `s^(-1)` |
