A 200 kg crate rests on a floor with carpet. A tired worker pushes with a horizontal force of 600 N on the crate initially resting on a thick pile carpet. The coefficients of static and kinetic friction are 0.60 and 0.40, respectively. Find the magnitude of the frictional force exerted by the surface of the crate by the carpet. Hint: Which type of friction acts in this case? What are the properties of different kinds of friction?

a block of mass m = 10.2 kg sitting on a ramp that makes an angle θ = 21° with the horizontal. This block is being pushed by a horizontal force F = 212 N. The coefficient of kinetic friction between the two surfaces is μ = 0.49. Write an equation for the acceleration of the block up the ramp using variables from the problem statement together with g for the acceleration due to gravity.  Find the acceleration of the block up the ramp in m/s2.

A block of mass M1 = 3 kg rests on top of another block of mass M2 = 5 kg. As shown in the figure, the top block is connected by a cord to a wall at left. The bottom block rests on a frictionless inclined plane of angle theta = 20o and has a force F applied to it down the plane. If the minimum force for which the bottom block will begin to slide has magnitude F = 2.5 N, what is the coefficient of static friction (us) between the two blocks?
