Once he gets it moving, 0.35 in now the sliding coefficient of the floor. If N. Noraa wants to maintain a net force of 10N (right), then how much applied force must he put on the furnace?

A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box the surface is 0.30, and the coefficient of kinetic friction is 0.20. What horizontal force must be applied to the box to cause it to start sliding along the surface?

The coefficient of static friction between the 3.00-kg crate and the 35.0˚ incline of Figure P4.31 is 0.300. What is the minimum force must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline?

The coefficient of static friction between the 3.00 kg crate and the 35.0 degree incline as shown in figure is 0.300. What minimum force F must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline?
