A cylindrical piece of cork of density of base area A and height h floats in a liquid of density $\rho_1.$ The cork is depressed slightly and then released. Show that the cork oscillates up and down simple harmonically with a period $\text{T}=2\pi\sqrt{\frac{\text{h}\rho}{\rho_1\text{g}}}$ where $\rho$ is the density of cork. (Ignore damping due to viscosity of the liquid).

A player throws a ball upwards with an initial speed of $29.4$ $m s ^{-1}$.
(a) What is the direction of acceleration during the upward motion of the ball?
(b) What are the velocity and acceleration of the ball at the highest point of its motion?
(c) Choose the $x = 0 ~ m$ and $t = 0 ~ s$ to be the location and time of the ball at its highest point, vertically downward direction to be the positive direction of $x$-axis, and give the signs of position, velocity and acceleration of the ball during its upward, and downward motion.
(d) To what height does the ball rise and after how long does the ball return to the player's hands?
(Take $g =9.8 ms^{-2}$ and neglect air resistance.)
