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. The pulley is a uniform disk with mass 11.3kg and radius 49.0cm and turns on frictionless bearings. You measure that the stone travels a distance 12.3m during a time interval of 2.50s starting from rest.(adsbygoogle = window.adsbygoogle || []).push({});

1. Find the mass of the stone.

2. Find the tension in the wire.

Free fall acceleration = 9.80 m/s^2

I'm not to sure what formula to use for this?
