Question

A bucket begins holding 25 kgs of sand. The bucket is to be
lifted to the top of a 15 meter tall building by a rope with
density 0.1 kg/m. However, the bucket has a hole in it, and leaks
0.2 kgs of sand each meter it is lifted.

Find the work done lifting the bucket and rope to the top of the
building. Use 9.8 m/s^{2} for gravity.

Answer #1

A leaky bucket full of sand has a mass of 25 pounds. The bucket
is to be lifted to the top of a building 15 feet tall by a rope
weighing 1 lb/ft. Every foot the bucket is lifted results in a loss
of 0.2 pounds of sand. Find the work done lifting the bucket to the
top of the building.

A bucket that has a mass of 10 kg when filled with sand needs to be
lifted to the top of a 25 meter tall building. You have a rope that
has a mass of 0.1 kg/m that must be secured to the bucket. It takes
1 meter of rope to secure the bucket. Once the bucket reaches the
top of the building it only has mass 8 kg because there was...

Calculus Thomas 14th edition. Ch.6.5, problem 13.
A 5 kg bucket lifted from the ground into the air by pulling in
20 m of rope at a constant speed. The rope weighs 0.08 kg/m. The
work spent on bucket and rope is 1136.8 J. Assume that the bucket
is leaking it starts with 5 liters of water (5 kg ) and leaks at
the constant rate. It finishes draining just as it reaches the top.

Create a bucket by rotating around the y axis the curve y = 3 ln
( x − 6 ) from y = 0 to y = 4. If this bucket contains a liquid
with density 880 kg/m3 filled to a height of 2 meters, find the
work required to pump the liquid out of this bucket (over the top
edge). Use 9.8 m/s2 for gravity.

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
