The coefficients of friction between a 1.5 kg block and a surface are μs = 0.50 and μk = 0.40. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is moving and the surface is inclined at 30o? Use g = 9.79 m/s2.

The coefficients of friction between a block of mass 1.5 kg and a surface are ?s = 0.60 and ?k = 0.40. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is at rest and the surface is inclined at 15o? Use g = 9.79 m/s2.

A 50-kg solid circular cylinder A rests on a 35-kg block B as
shown in Fig. P16-112. When a force F is applied to the block, the
block accelerates at a rate of 5 m/s2. If the coefficients of
friction between the block and the cylinder and between the block
and the horizontal surface are both μs = μk = 0.25, determine the
magnitude of F and the frictional force exerted by the block on the
cylinder.

To understand kinetic and static friction. A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction is μk, with μk<μs. a- Suppose you want to move the block, but you want to push it with the least force possible to get it moving. With what force F must you be pushing the block just before the block begins to move? Express the...
