A block of mass m is at rest at the origin at t=0. It is pushed with constant force f0 from x=0 to x=l across a horizontal surface whose coefficient of kinetic friction is μk=μ0(1−x/l). That is, the coefficient of friction decreases from μ0 at x=0 to zero at x=l.

i dont the the options but i believe its (oversee business) sorry if im wrong tho
