An anchor of mass 500kg is attached to a light cable that passes over a roller of negligible mass and winds around a hollow cylindrical drum of radius 1.2m and mass 250kg which can rotate around a frictionless axel. The anchor is released and drops 18m to the surface of the water. Use energy considerations to calculate the angular velocity of the drum when the anchor hits the water.
