A stone is suspended from the free end of a wire that is wrapped around the outer rim of a pulley, as shown in the figure (see the figure ). The pulley is a uniform disk with mass 11.9 kg and radius 47.0 cm and turns on frictionless bearings. You measure that the stone travels a distance 12.7 m during a time interval of 2.55 s starting from rest.

Find the mass of the stone.
