Our 10.0-kg mystery box rests on a horizontal floor. The coefficient of static friction is 0.40 and the coefficient of kinetic friction is 0.30. Determine the force of friction, acting on the box if a horizontal applied force is exerted on it of magnitude: (a) 0, (b) 10 N, (c) 20 N Use 9.81m/s sqaured for the gravity and also F sub A unit for the applied force

A crate of mass 18.0 kg rests on a level surface. If the coefficient of kinetic friction between the crate and surface is 0.430, calculate the following. (a) Calculate the normal force.

(Give the magnitude.) X N (d) Calculate the magnitude of the kinetic friction force when the 92.0-N applied force is exerted at an angle of 37.5° above the horizontal. X N

A box with a mass of 0.5 slugs lies on an inclined plane making an angle of 30o with the horizontal.  If the coefficient of kinetic friction between the box and the plane is 0.4, what is the magnitude of the force that must be applied parallel to the incline to keep the box moving down the incline at a constant speed?
