SHM of a Floating Object An object with height h, mass M, and a uniform cross-sectional area A floats upright in a liquid with density p.

(a) Calculate the vertical distance from the surface of the liquid to the bottom of the floating object at equilibrium.

(b) A downward force with magnitude F is applied to the top of the object At the new equilibrium position, how much farther below the surface of the liquid is the bottom of the object than it was in part (a)? (Assume that some of the object remains above the surface of the liquid.)

(c) Your result in part (b) shows that if the force is suddenly removed, the object will oscillate up and down in SHM. Calculate the period of this motion in terms of the density P of the liquid, the mass M, and cross· sectional area A of the object. You can ignore the damping due to fluid friction (see Section 13.7).
