- Calculating force under a liquid medium
Main Question or Discussion Point
I'm trying to determine the force needed for one object to displace another object underwater. Specifically, Object A strikes Object B hard enough to jettison it from the seafloor up to sea level/land, let's say the Pacific coastline. I have a timeframe in mind, density & mass of the two objects, and distance traveled, yet don't know how to apply these factors under the liquid medium of the sea and the pressures involved. I'm not asking for easy answers so much as perhaps an equation to simplify things a bit to calculate either the force required to achieve such a feat or the energy output such a collision would yield.
