A block of mass 4 kg is kept over a rough horizontal surface. The coefficient of friction between the block and the surface is 0.1 At, t=0, (3hati)(m/s) velocity is imported to the block simultaneously (-2hati)N force starts acting on it. Its displacement in first 5s is

A block of mass 1 kg in kept on a rough horizontal surface with mu_(s)=0.1 . A force of 0.5 N is applied as shown in the figure. What is the frictional force applied by ground on the block?
