A block of mass m is moving on a rough horizontal surface. mu is the coefficient of kinetic friction between the block and the surface. What is the net force exerted by the surface on the block?

A block of mass 6 kg is being pulled by force 24 N as shown . If coefficient of friction between the block and the surface is 0.6 , frictional force acting on the block is :

A block of mass M is kept on as rough horizontal surface. The coefficient of static friction between the block and the surface is mu . The block is to be pulled by applying a force to it. What minimum force is needed to slide the block? In which direction should this force act?

A block of mass M rests on a rough horizontal surface as shown. Coefficient of friction between the block and the surface is mu . A force F=mg acting at angle theta with the vertical side of the block pulls it. In which of the following cases the block can be pulled along the surface?

A block of mass 1kg lies on a horizontal surface in the truck, the coefficient of friction between the block and the surface is 0.6. If the acceleration of the truck is 5ms^(-2) the frictional force acting on the block is
