Static And Kinetic Friction

A block of mass 5 kg is lying on a rough horizontal surface. The coefficient of static and Kinetic friction are 0.3 and 0.1 and g=10m//s^(-2) If a horizontal force of 50N is applied on the block, the frictional force is

A block of mass 2 kg is pressed against a rigid vertical wall by a horizontal force of 100 N. If co-efficient of static and kinetic friction are each equal to 0.3 then find the magnitude and direction of frictional force on the block.

A force of 750 N is applied to a block of 100 kg to prevent it from sliding down an inclined plane of 30^(@) inclination. If coefficients of static and kinetic friction are 0.4 and 0.2, the frictional force acting is :

A uniform disc of mass m and radius R is rolling up a rough inclined plane which makes an angle of 30^@ with the horizontal. If the coefficients of static and kinetic friction are each equal to mu and the only force acting are gravitational and frictional, then the magnitude of the frictional force acting on the disc is and its direction is .(write up or down) the inclined plane.
