What length of cord is pulled from the spool

Reference no: EM1347822

Q. A 4.00 m length of light nylon cord is wound around a uniform cylindrical spool of radius 0.500 m and mass 1.00 kg. The spool is mounted on a frictionless axle and is initially at rest. The cord is pulled from the spool with a constant acceleration of magnitude 2.50 m/s2.

(a) How much work has been done on the spool when it reaches an angular speed of 6.90 rad/s?

(b) Assuming that there is enough cord on the spool, how long does it take the spool to reach this angular speed?
