A cyclist is moving on a straight, level road, as illustrated in Fig. 1.1.
(a)[3]
Describe a method for measuring the cyclist’s average speed. In your response, state the equipment used, the measurements taken and the way the average speed is found.
(b(i))[1]
State what negative acceleration means.
(b(ii))[2]
The magnitude of the acceleration is $1.8\,\text{m s}^{-2}$. Calculate the change in speed of the cyclist in $2.5\,\text{s}$.
