22M.2.HL.TZ2.a.ii

An experiment to investigate simple harmonic motion consists of a mass oscillating at the end of a vertical spring.

The mass oscillates vertically above a motion sensor that measures the speed of the mass. Test 1 is carried out with a 1.0 kg mass and spring of spring constant $k_{1}$ . Test 2 is a repeat of the experiment with a 4.0 kg mass and spring of spring constant $k_{2}$ .

The variation with time of the vertical speed of the masses, for one cycle of the oscillation, is shown for each test.

Deduce $\frac{k_{1}}{k_{2}}$ .
