Power applied to a particle varies with time as `P=(4t^(3)-5t+2)` watt, where t is in second. Find the change its K.F. between time t = 2 and t = 4 sec.

Power applied to a particle varies with time as P =(3t^(2)-2t + 1) watt, where t is in second. Find the change in its kinetic energy between time t=2s and t = 4 s .

Power applied to a particle varices with time as P =(3t^(2)-2t + 1) watt, where t is in second. Find the change in its kinetic energy between time t=2s and t = 4 s .

Power applied to a particle varices with time as P =(3t^(2)-2t + 1) watt, where t is in second. Find the change in its kinetic energy between time t=2s and t = 4 s .

Power delivered to a paticle varies with time as P = (3t^(2) - 2t) watt, where 't' is in seconds, then change in its kinetic energy between time t = 1 to t = 3s .
