2.) A block with mass $m = 0.47$ kg sits on inverted cone that makes the angle $\theta = 32^\circ$ with the horizontal. The distance between the bottom of the cone and the mass is $L = 2.5$ m. The coefficients of kinetic and static friction between the block and the cone are $\mu_k = 0.56$ and $\mu_s = 0.67$, respectively. The inverted cone rotates with period $T = 5.4s$. a) Find the centripetal acceleration of the block! $a_c = \frac{v^2}{r}$ b) Draw the appropriate free-body diagram! c) Write down the appropriate Newton's second law!
