19M.3.HL.TZ1.b
The graph shows the variation with time t of the total energy E of a damped oscillating system.
Another system has the same initial total energy and period as that in (a) but its Q factor is greater than 25. Without any calculations, draw on the graph, the variation with time of the total energy of this system.
