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;(b) the acceleration of the masses when m21m1 = >

Two masses m1 and m2 are attached to a string which passes over a frictionless smooth pulley. When m1 = 10 kg, m2 = 6 kg, the acceleration of masses is  gn𝑔𝑛. Value of n, is

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?

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?

1(a).Given is a box (Object 1 with a mass of 𝑚 ) on a table connected to a1= 1 𝑘𝑔box is a rope which has no mass. The rope passess over a frictionless, masslesspulley and is fixed to another box (Object 2 with a mass 𝑚 ). The pulley has2= 2 𝑘𝑔a fixed position and cannot move left, right up or down. Object 1 is being accelerated5. 41 𝑚/𝑠2. What is the friction coefficient of Object 1 and table top? Assume𝑔 = 9. 8 𝑚/𝑠2 and let us agree that moving to the left is the positive direction ofobject 1.(b) Object 𝑀 on inclined at an angle connected to a rope with no1= 20 𝑘𝑔 α = 20°mass. The rope passes over frictionless, massless. Pulley is fixed to the ceiling andcannot move. Pulley is hanging on a rope through which a second box is attached.Pulley moves up if object 1 goes down the incline. static and kinetic coefficientµ. Find the so object 1 is not moving.
