A block of mass m 4 kg is kept on a rough surface of 0 25 At t 0 an external force F t that varies linearly with time starts acting on the block The force acts for a duration of 8 sec only and F t 8 0 N If the block starts moving at t 2 sec and finally stops at t 11 sec then find the time in sec instant when velocity acquired by the block is maximum m F
