A bucket and a counter-weight are used to lift water out of a well. The bucket and counter-weight are attached to either end of a light rope that passes over a light, frictionless pulley, with the rope hanging straight down to both. The mass of the counter-weight is greater than the mass of the bucket filled with water. The bucket starts at the bottom of the well and the counter-weight starts at the top. The counter-weight is released from rest and starts to descend. After the counter-weight has dropped 1.50 m, its speed is 3.00 m/s.
A) If the total mass of the bucket with water and counterweight is 19.5 kg , what is the mass of the counter-weight?
B) If the total mass of the bucket with water and counterweight is 19.5 kg , what is the mass of the filled bucket?

Two blocks with different masses m1 and m2 and m1 is larger than m2. They are attached to either end of a light rope that passes over a light, frictionless pulley suspended from the ceiling. The mass are released from rest, and the more massive one starts to descend. After this block has descended 1.6 m, its speed is 2.2 ms-1. If the total mass is 4.1 kg, what is the mass of the heavier block m1 (unit is kg)?...

A bucket that weighs 6 lb and a rope of negligible weight are used to draw water from a well that is 50 ft deep. The bucket is filled with 36 lb of water and is pulled up at a rate of 2.5 ft/s, but water leaks out of a hole in the bucket at a rate of 0.25 lb/s. Find the work done in pulling the bucket to the top of the well. Show how to approximate the required...

A bucket of water of mass 14.4 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350 m with mass 13.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.0 m to the water. You can ignore the weight of the rope. Take the free fall acceleration to be g = 9.80...
