Question

A bucket weighing 2 kg and a rope of negligible mass is used todraw water from a well that is 40.8 meters deep. Just before thebucket starts being raised from the bottom of the well, the bucket isfilled with 6 kg of water. Unfortunately, there is a hole in the bucketand water leaks out at the rate of 0.12 kg per second. The bucketis pulled up at a constant rate of 0.8 meters per second.(a)How much water is in the bucket when the bucket reaches thetop of the well?(b)Find the work done pulling the bucket to the top of the well.(Assume that the acceleration of gravity is 9.8 meters per secondper second.)

3. A bucket weighing 2 kg and a rope of negligible mass is used to draw water from a well that is 40.8 meters deep.

(a) How much water is in the bucket when the bucket reaches the top of the well? (b) Find the work done pulling the bucket to the top of the well. (Assume that the acceleration of gravity is 9.8 meters per second per second.)
