Given:
Initial velocity, u = 0 m/s
Final velocity, v = 60 m/s
time taken, t = 5 sec
Work done is nothing but the change in KE of an object.
Work done, ΔKE = 1/2 m(v2- u2)
but value of mass should have been given!
Similarly we can calculate Power consumed as time rate of work done, P = dW/dt
Initial velocity, u = 0 m/s
Final velocity, v = 60 m/s
time taken, t = 5 sec
