Physics

Suppose you have a system of two masses strung over a pulley.Mass 1 (6.7 kg) hangs on the right side of the pulley suspendedover the ground at height 1.2 m. Mass 2 (2.5 kg) hangs over theleft side of the pulley and rests on the ground. The pulley is auniform disk of mass m and radius 11.3 cm. When the system isreleased, Mass 1 moves down and Mass 2 moves up, such that Mass 1strikes the ground with speed 1.1 m/s. This is called an AtwoodMachine. Calculate the mass of the pulley in kg.
