    Force of friction on different times

    Homework Statement A 3.280 kg block of wood rests on a steel desk. The coefficient of static friction between the block and the desk is μs = 0.605 and the coefficient of kinetic friction is μk = 0.155. At time t = 0, a force F = 12.0 N is applied horizontally to the block. State the force of...
