CAPE Physics Unit 1 · 1999 · Paper 2 · Question 1(a)

A rubber ball is thrown vertically upwards from a tennis gun with an initial speed of 14 m/s. Figure 1 shows its velocity-time graph.

Describe a possible experiment that you could perform to obtain the data for the velocity - time graph shown in Figure 1.

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