The kneejoint is lubricated by synovial fluid so that the coefficient of static friction between the bones is 0.0200 and the coefficient of kinetic friction is 0.0160. If a person supports 40.0 kg of their mass on one knee, what is the maximum frictional force in that knee? Enter your answer in N. Do not enter any units. A 5.35 kg block is being pushed along a horizontal surface by a force of F3I = 65.5 N directed at an angle of 8 = 13.5 below the horizontal, as shown in Figure 1. The coefficient of kinetic friction between the box and the surface is 0.319. What is the acceleration of the box? Enter your answer in mfsz
