A 9.0-m-long string is wrapped around a pulley that is free to rotate a pulley that is free to rotate about a fixed axle. The pulley has a radius of 6.0 cm and initially is at rest. The thickness of the string is negligible. Someone pulls on the free end of the string, thereby unwinding it and giving the pulley an acceleration of +17.0 rad/s². (a) Through what angle has the pulley rotated when the string is completely unwound? (b) What is the final angular velocity of the pulley?

A 9.0-m-long string is wrapped around a pulley that is free to rotate a pulley that is free to rotate about a fixed
axle. The pulley has a radius of 6.0 cm and initially is at rest. The thickness of the string is negligible.
Someone pulls on the free end of the string, thereby unwinding it and giving the pulley an acceleration of
+17.0 rad/s². (a) Through what angle has the pulley rotated when the string is completely unwound? (b)
What is the final angular velocity of the pulley?
