Problems Written Atmospheric Buoyancy Neglected Q29170603

The problems are written such that atmosphericbuoyancy can(and should) be neglected.

2 Rock the boat (a) Imagine a box of total height H, density p, and horizontal area A. If it is upright but depth D of it is submerged under water of density Pa, what is the net force on it? (b) Ts, what is the equilibrium depth D at which tex oats? (c) Define Do D to be how far above equilibrium the box currently is. Show that Fuet-yfor (d) Hey that’s Hooke’s law! So the box will hob sinusoidally like a spring. What’s the period of this (e) Barges are roughly box-shaped. If you’re riding one and feel it bobbing slightly once every 3.5 s, how kPwAg harmonic motion? Write it in terms of just Do and g. far below the waterline an yu conclude the hul extends?
