A string is wrapped around the edge of a uniform cylinder of radius R=20 cm and mass M= 5kg which is initially resting motionless on a frictionless table. The end of the spring is pulled with a force of 71N for 0.6m. If the linear speed of the cylinder is found to be 2.38328 m/s, what is the angular speed of the cylinder in (rad/s)?
