Academics

Q. A ship's anchor weighs 5000 N. Its cable passes over a roller of negligible mass and is wound around a hollow cylindrical drum of mass 380kg and radius 1.10m. The drum is mounted on a frictionless axle. The anchor is released and drops 16 m to water.

Use energy considerations to find out the drum's rotation rate when the anchor hits water. Avoid the mass of the cable.
