Imagine a frictionless pulley in the shape of a solid cylinder of unknown mass M M and radius 0.16 m that is used to draw water from a well. A bucket of mass 1.5 kg is attached to a cord wrapped around the cylinder. The bucket starts from rest at the top of the well and falls for 2.5 s before hitting the water at a distance of 6 m below the top of the well. Neglect the mass of the cord.Calculate the mass of the pulley using the moment of inertia
