Figure shows a block of mass m resting on a 20? slope. The block has coefficients of friction 0.82 and 0.49 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0 kg. What is the minimum mass m that will stick and not slip? If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have?

Figure shows a block of mass m resting on a 20? slope. The block has coefficients of friction 0.77 and 0.46 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0 kg. What is the minimum mass m that will stick and not slip? If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have?

Please help, I dont understand this... A block of mass m1 = 34 kg on a horizontal surface is connected to a mass m2 = 16.5 kg that hangs vertically as shown in the figure below. The two blocks are connected by a string of negligible mass passing over a frictionless pulley. The coefficient of kinetic friction between m1 and the horizontal surface is 0.23. (a) What is the magnitude of the acceleration (in m/s2) of the hanging mass? (b)...

Three objects are connected by weightless flexible strings as shown in the figure. The pulley has no appreciable mass or friction, and the string connected to theblock on the horizontal bench pulls on it parallel to the bench surface. The coefficients of friction between the bench and the block on it areμs = 0.660 and μk = 0.325. You observe that this system remains at rest. Find (a) the mass of and (b) the friction force on theblock on the...

Investigation 1 - Connected Particles (Maximum Mark 45) A block mass M kg is resting on the horizontal top of a cube. The coefficient of friction between the block and the cube is u. Two strings are attached to the sides of the block. One string passes over a pulley and is attached to an object of mass m kg which is hanging freely a height h metres above the ground. The other string passes over another pulley on the...

In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...
