5J A person applies a force of magnitude F as shown to the axle of a uniform disc with mass Mand radius R (such that the force is applied at the center of mass of the disc). The ground has a coefficient of static friction of 0.500 and a coefficient of kinetic friction of 0.400. a) Below a critical F, the disc rolls without slipping. Find this critical F in terms of M, R, and g. F b) Calculate the...
