Question

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 (Figure 1) ). The pulley is a uniform disk with mass 11.6kg and radius 54.0cm and turns on frictionless bearings. You measure that the stone travels a distance 13.0m during a time interval of 2.50s starting from rest.

Find the mass of the stone.

Find the tension of the wire.
