Physics help please?

Consider an RC circuit already charged. The energy stored in the capacitor was determined as a function of time as the switch was closed and the capacitor was discharging. What is the best estimate of the time constant for the RC circuit?

Please show work.

    One time constant correlates to 36.8% of the maximum, or in this case

    U = 5J * 0.368 = 1.84 J

    Just eyeballing on the graph, I'd say that corresponds to 3.5 seconds or so.
