CSEC Physics · 1997 · Paper 2 · Question 2(d)

St. Lucia is 80 km due south of Martinique. A small aeroplane flies from Martinique to St. Lucia on a day when a strong wind of 50 km h⁻¹ is blowing from the east, as shown in Figure 6.

The pilot flies the plane at 80 km h⁻¹, due south relative to the air. Use a scale diagram to find with what velocity and in what direction the plane will travel relative to the Earth.

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