Alight, flexible rope is wrapped several times around a hollow cylinder with a weight of 40.0 n and a radius of 0.25 m, that rotates without friction about a fixed horizontal axis. the cylinder is attached to the axle by spokes of a negligible moment of inertia. the cylinder is initially at rest. the free end of the rope is pulled with a constant force p for a distance of 5.00 m, at which point the end of the rope is moving at 6.00 m/s. if the rope does not slip on the cylinder, what is the value of p?
