The two graphs in the figure are for two different vertical mass/spring systems. What is the frequency of system A? (answer in Hz) What is the first time at which the mass of system A has maximum speed while traveling in the upward direction? (answer in s) What is the period of system B? (answer in s) What is the first time at which the mechanical energy of system B is all potential? (answer in s) If both systems have the same mass, what is the ratio Ka /Kb of their spring constants?
