A bucket that has a mass of 20 kg when filled with sand needs to be lifted to the top of a 30 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 13 kg because there was a hole in the bottom and sand was leaking out at a constant rate while it was being lifted to the top of the building. Find the work done lifting the bucket (sand and rope) to the top of the building. Joules

Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

Transcribed Image Text:A bucket that has a mass of 20 kg when filled with sand needs to be lifted to the top of a
30 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 13 kg because there was a hole in the bottom and
sand was leaking out at a constant rate while it was being lifted to the top of the
building.
Find the work done lifting the bucket (sand and rope) to the top of the building.
