A fixed pulley carries a weightless thread with masses m1and m2at its ends. There is friction between the thread and the pul-ley. It is such that the thread starts slipping when the ratio m2im1 == ry a. Find:(a) the friction coefficient;

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of ½ MR2. If m1 is 4.00 kg, m2 is 4.00 kg, and M is 4.00 kg, then what is the tension in the string attached to m2?

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless incline as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of ½ MR2. If m1 is 2.00 kg, m2 is 1.00 kg, M is 4.00 kg, and the angle is 60.0 degrees, then what is the acceleration of m1?

An object of mass m1 = 4.90 kg is connected by a light cord to an object of mass m2 = 3.00 kg on a frictionless surface (see figure). The pulley rotates about a frictionless axle and has a moment of inertia of 0.440 kg · m2 and a radius of 0.320 m. Assume that the cord does not slip on the pulley.An illustration shows a rectangular block of mass m2 on the horizontal surface of a table. Block m2 is connected to another rectangular block of mass m1 by a cord that runs over a pulley placed diagonally at the corner of the horizontal surface of the table.
