    3. (15 pts) Consider the arrangement of pulleys and blocks shown in the figure below. The pulleys are assumed massless and frictionless and the connecting strings are massless and unstretchable. Denote the respective masses as ma and mß. The uppermost pulley in the figure is free to rotate but its center of mass does not move. All pulleys have the same radius R.

    a=g(ΔmmT)m/s2 For a frictionless pulley, g is the free fall acceleration due to gravity but in practice, pulleys have friction so g is smaller. Assume your pulley has friction such that g=9 m/s2. You hang two masses on either side of your pulley. M1 has a mass of 169 g. M2 has a mass of 277 g. What is the acceleration of the masses as they fall?

    Two masses are tied to the ends of a rope, and the rope is draped over a pulley. This arrangement is known as "Atwood's machine." Assume the rope and pulley are massless and there is no friction in the pulley. When the masses are of 20.5 kg and 14.7 kg, calculate the magnitude of their acceleration, a, and the tension in the rope, T. Take g = 9.81 m/s2. Use Free Body Diagrams to support your analysis.

    Please show all work, equations used, and free body diagram. Two masses are connected by a string (ignore the mass of the string), one is on an incline and the other is being suspended by a pulley in the air (Pulley is also massless and frictionless). The higher object (m1) is 5 kg and is sitting on the incline and is experiencing friction. The incline is 20 degrees from the horizontal and has a coefficient of kinetic friction Uk=0.35. The...

    A device known as Atwood’s machine consists of two masses hanging from the ends of a vertical rope that passes over a pulley. Assume the rope and pulley are massless and there is no friction in the pulley. Mass mA is greater than mass me. Find expressions for the magnitude of their acceleration, a, and the tension in the rope, T. Express your answers in terms of the masses and g, the acceleration due to gravity.
