A 100 N box is initially at rest on a rough horizontal surface. The coefficient of static friction between the block and the surface is 0.6 and the coefficient of kinetic friction is 0.4. A man decides to move the box so he applies a steadily increasing horizontal force F_Applied on the box to the right as shown. The graph on the left below shows the horizontal force F_Applied on the box as it goes from 0 to 80 N...

A block of mass M is sitting on a friction-less horizontal surface. A second block of mass m is sitting on top of the first block. The (horizontal) interface between the two blocks is characterized by a static friction coefficient µ. The acceleration of gravity is g. Find the max horizontal force F that can be applied to the lower block such that the upper block does not slide off it.

A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of p. The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of 0 with the horizontal. The box was initially travelling to the right at speed v = 1.3" If M =9.7kg,...
