Use the figure to the right to answer the next two problems. A ball of mass m = 100 g and radius r = 10 cm is suspended from a light spring with spring constant k = 4 N / m.The ball is then immersed in oil with viscosity = 0.2 Pa.s and driven at the resonant frequency by a variable force F = F0 cos (t) at an amplitude of A = 10 cm.
