how do you calculate the force of a falling piano? this work would be equal to the change in kinetic energy. since the piano starts from rest, the initial kinetic energy is zero.
impact on water is a very complex topic. your simple calculation just figures out the velocity of a free-falling body after a 50 m drop. that just tells you the initial relative velocity of body and water surface. it doesn't tell you much about the force at impact, or whether the person survived.

during an impact, the energy of a moving object is converted into work, and force plays an important role. to create an equation for the force of any impact, you can set the equations for energy and work equal to each other and solve for force. from there, calculating the force of an impact is relatively easy.

how to calculate and convey the true cost of downtime. or any other manner that helps your audience understand and appreciate the impact. you can calculate the approximate costs by using
russ_watters states that the force of impact is the same as the static pressure from the system. my question is, how can that be? if you take a hose and turn it on such that you get a gentle, steady flow of water, and turn it toward an object, lets say a piece of cardboard hanging conveniently in front of you, the water will move the cardboard
