CSEC Physics · January 2018 · Paper 2 · Question 3(c)(ii)

Figure 4 shows a pendulum of mass 0.5 kg oscillating in a vacuum. X is the lowest position of the pendulum, where its maximum speed is 1.8 ms⁻¹.

Use the principle of conservation of energy to find the maximum gravitational potential energy of the pendulum.

This question uses a figure or table from the paper — you'll see it when you practise.
