Suppоse the cоefficient оf stаtic friction of а surfаce is  0 . 600  and the coefficient of kinetic friction of the surface is  0 . 550 . The surface is a  30 . 0 °  incline. Block A of mass  20 . 0   k g  rests on the surface, as shown in Fig. 2.1, (a) what is the magnitude and direction of the frictional force? Block A is attached to an string that is parallel to the surface and passes over an ideal pully, and block B is attached to the dangling end of the string, as shown in Fig. 2.2. If the mass of block B is  5 . 00   k g  and block A is at rest, (b) what is the magnitude and direction of the frictional force on block A. If the mass of block B can be changed, (c) what is the mass of block B for block A to be at the verge of moving up the inclined surface? If the mass of block B is  25 . 00   k g , (d) what is the magnitude of acceleration of block A, and (f) what is the magnitude of tension on the string? q18_phys2425_spr2025.jpg
