Q1Physical Quantities and MeasurementKinematicsFree sample

A cyclist travels along a straight, horizontal road, as shown in Fig. 1.1.

Fig. 1.1

(a)

Describe how the average speed of the cyclist can be measured.

In your account, suggest what equipment is used, the measurements that are made and how the average speed is calculated.

(b)

For part of the journey, the cyclist has a constant, negative acceleration.

(i)

State what is meant by a negative acceleration.

(ii)

The size of the acceleration is $1.8\ \text{m / s}^2$ .

Calculate the change in speed of the cyclist in a time of $2.5\ \text{s}$ .

change in speed = ______
