A package of mass 36 kg is being pulled by force of 215 N parallel to a horizontal surface. The coefficient of kinetic friction between the package and the surface is 0.35. If the package moves a distance of 9.1 m, what is the resultant work?

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?
