The drum shown in the figure has a radius of 0.40 m and a moment of inertia of 2.3

\mathrm { kg } \cdot \mathrm { m } ^ { 2 }

about an axis perpendicular to it through its center.The frictional torque at the drum axle is 3.0 N ∙ m.A 14-m length of rope is wound around the rim.The drum is initially at rest.A constant force is exerted on the free end of the rope until the rope is completely unwound and slips off.At that instant,the angular speed of the drum is

23 \mathrm { rad } / \mathrm { s }

The drum then slows down at a constant rate and comes to a halt.In this situation,what was the magnitude of the constant force that pulled the rope? $The drum shown in the figure has a radius of 0.40 m and a moment of inertia of 2.3 \mathrm { kg } \cdot \mathrm { m } ^ { 2 } about an axis perpendicular to it through its center.The frictional torque at the drum axle is 3.0 N ∙ m.A 14-m length of rope is wound around the rim.The drum is initially at rest.A constant force is exerted on the free end of the rope until the rope is completely unwound and slips off.At that instant,the angular speed of the drum is 23 \mathrm { rad } / \mathrm { s } The drum then slows down at a constant rate and comes to a halt.In this situation,what was the magnitude of the constant force that pulled the rope?
