A massless string is wrapped around a solid 7.6-kg cylinder of diameter 24 cm that can rotate freely without friction about an axis through its center. A stone is tied to the loose end of the string. When the stone is released from rest, the cylinder turns without the string slipping. If the cylinder has an angular velocity of 26 rad/s after 1.4 s, what is the mass of the stone? Through how many revolutions does the cylinder turn in this time?
