As shown below, a 56 kg box is pulled by a 648 N force at an angle of 210 from the horizontal. The coefficient of kinetic friction is 0.2. Find the acceleration of the box. F. FA 86 kg sled slides down an inclined plane with an angle 13. The kinetic friction coefficient is 0.2. What force, directed down and parallel to the plane, will produce an acceleration of 12 m/s2?A 8 kg object is dragged up a slope of 38 with a kinetic friction coefficient of 0.2. What force, parallel to the slope, would be needed to produce an acceleration of 3 m/52?A toy box of 8.3 kg of mass is being pulled on the floor by Alphonse and Bernard. The coefficients of kinetic and static friction between the box and the horizontal floor are 0.58 and 0.66. If Alphonse exerts 41.3 N and the box acceleration is 1.04 m/s2, what is the force exerted by Bernard?Albert tries to move a desk of 25.5 kg of mass that is at rest on a horizontal surface. The desk barely starts sliding as soon as Albert exerts 55.6 N. What is the coefficient of friction between the desk and the surface
