A block of mass m is moving on a rough horizontal surface where coefficient of friction between block and surface is µ = 0.5. At t = 0 block is moving with a velocity 
then a horizontal force F = 2t is applied on it in the direction of velocity. Here t represent time then the speed of block after the application of force-
