CAPE Physics Unit 1 · May/June 2021 · Paper 2 · Question 1(a)

A parachutist falls from an airplane. Recorded velocities, v, and times, t, are shown in Table 1.

On the grid provided in Figure 1 on page 7, plot a graph of velocity versus time. Draw the best smooth curve through the points.

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