The Table shows the displacement of a racing car at different times as it travels along a straight track during a speed trial. Determine the car’s velocity.

Displacement $/\mathrm{m}$	$0$	$85$	$170$	$255$	$340$
Time $/\mathrm{s}$	$0$	$1.0$	$2.0$	$3.0$	$4.0$

 The Table shows the displacement of a racing car at different times as it travels along a straight track during a speed trial. 

 Draw the displacement-time graph and use it to find the car's velocity.

An old car travels due south. The distance it travels at hourly intervals is shown in the table

Draw the distance-time graph to represent the car journey.

An old car travels due south.The distance it travels at hourly intervals is shown in the table

From the distance-time graph deduce the car's speed in ${\mathrm{kmh}}^{-1}$ during the first three hours of the journey

An old car travels due south. The distance it travels at hourly intervals is shown in the table

What is the car's average speed in ${\mathrm{kmh}}^{-1}$ during the whole journey,

You walk $3.0 \mathrm{km}$ due north and then $4.0 \mathrm{km}$due east.

Calculate the total distance in $\mathrm{km}$ you have travelled.

You walk $3.0 \mathrm{km}$ due north and then $4.0 \mathrm{km}$due east. Make a scale drawing of your walk, and use it to find your final displacement. Remember to give both the magnitude and the direction.

Check your answer by calculating your displacement.

A student walks $8.0 \mathrm{km}$ southeast and then $12 \mathrm{km}$ due west.

Draw a vector diagram showing the route. Use your diagram to find the total displacement.Remember to give the scale on your diagram and to give the direction as well as the magnitude of your answer.
