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 mass13 kg and radius 31.0cm and turns on frictionless bearings. You measure that the stone travels a distance 12.7 m during a time interval of 3.50s starting from rest.

1) Find the mass of the stone.

2) Find the tension in the wire
