CAPE Physics Unit 1 · 2015 · Paper 2 · Question 2(b)(i)

Figure 3 shows a block oscillating horizontally between two identical springs, each with spring constant, k. The vibrator has a constant amplitude. As the frequency is changed, the amplitude of oscillation of the block is measured. Table 2 shows the data recorded.

On the grid provided in Figure 4 (page 9), plot a graph of amplitude of oscillation, y, against frequency, f.
