A moored contact mine is an explosive tethered by a cable to the seafloor so that it sits just under the surface of the ocean, then explodes when a ship hits it. Imagine one is a 300 kg sphere with a radius of 0.600 m. If it is 4.00 m below the surface and the tether is low mass enough to be negligible, what is the tension in the tether?
Pbot = ptop + density*g*height
pbot = 101300 + (1030)(9.81)(4)
F/A = 141717.2
F = 141717.2 * pi * .6^2
F = 160197.1N
Is this force the correct force which I am trying to find?
