Item 4 To start her lawn mower, Julie pulls on a cord that is wrapped around a pulley. The pulley has a moment of inertia about its central axis of I = 0.660Kg(metersquared) and a radius of 6.00cm . There is an equivalent frictional torque impeding her pull of Torque of friction = 0.380 meter times Newtons. A:To accelerate the pulley at an angular acceleration of 4.70rad/secondsquared , how much torque does Julie need to apply to the pulley? B:How much tension must be exerted on the rope?
