Two blocks of mass M1 and M2 are connected by a massless string that passes over a massless pulley as shown in the figure. M1 has a mass of 8.75 kg and rests on an incline of M2 01 = 63.5°.

Fy m +x P On the left a mass, 17.9 kg, is at rest. Force Pis acting on the mass in the (Fx) direction as shown. The coefficient of static friction between the mass and the surface is μ = 0.855. The coefficient of kinetic friction between the mass and the surface is µ = 0.565. What is the greatest force P that can be applied and the mass will remain at rest?
A horizontal force F pushes against a block of mass m. The mass m in turn pushes against a bigger block of mass M. There isn't friction any between the larger block and the table, but there is friction in between the blocks (coef. of static friction is μs). What's the smallest force F that will hold the smaller mass m m against the larger mass M without letting the smaller mass m fall down?
Two boxes (Box A = 9.7 kg and Box B = 5.4 kg) are connected by acord running over a pulley. The coefficient of kinetic friction betweenbox A and the table is 0.18. We ignore the mass of the cord and pulleyand any friction in the pulley, which means we can assume that a forceapplied to one end of the cord will have the same magnitude at theother end. We wish to find the tension of the cord while accelerating (inN), assuming the cord doesn’t stretch. As box B moves down, box Amoves to the right. Hint: Solve for the acceleration of the system first.
A light rope is attached to a block with mass 4.00 kg that restson a frictionless, horizontal surface. The horizontal rope passes overa frictionless, massless pulley, and a block with mass m is suspendedfrom the other end. When the blocks are released, the tension in therope is 15.0 N. Draw two free-body diagrams: one for each block.
