A 15kg block is initially moving along a smooth horizontal surface with a speed of v=4m//s to the left. It is acted by a force F , which varies in the manner shown. Determine the velocity of the block at t=15 seconds.

A block of mass 2kg is resting on a rough horizontal surface.The coefficients of static and kinetic frictions between the block and surface are 0.7 and 0.6 respectively.A horizontal force F=(4N/s)times t is applied on the block at t=0.At t=4s ,the force of friction on the block is (take g=10m/s^(2) )
