Here is this week's POTW:
A fire helicopter carries a bucket of mass $m$ at the end of a cable. Flying back from a fire with an empty bucket at a constant speed, the cable makes an angle $\alpha$ with respect to the vertical.
(a) Determine the force of air resistance on the bucket.
(b) After filling the bucket with sea water, the helicopter returns to the fire at the same speed with the bucket now making an angle $\beta<\alpha$ with the vertical. What is the mass of the water in the bucket?
