Assume that the Titanic is drifting in Southampton harbor before its fateful journey and the captain wishes to stop the drift by dropping an anchor. The iron anchor has a mass 1000 kg. It is attached to a massless rope. The rope is wrapped around a reel in the form of a solid disk of radius 0.350 m and mass 300 kg, that rotates on a frictionless axle.
(a) Find the angular displacement of the reel when the anchor moves down 15.0 m.
___rad
(b) Find the acceleration of the anchor as it falls through the air, which offers negligible resistance.
____m/s2
(c) While the anchor continues to drop through the water, the water exerts a drag force of 2500 N on it. With what acceleration does the anchor move through the water?
____m/s2
(d) While the anchor drops through the water, what torque is exerted on the reel?
____N·m
I haven't done this kind of material for a while now, and as I look back at this problem I am unsure how to attempt it...
