3. 5 Walking to work
A simplified distance time (s - t) graph of a teachers walk to work one morning is given below s
(m)
t (mins)
Task 1a:
Explain the shape of the graph by describing what might have happened at each stage of the journey. Sketch a Velocity time (v – t) graph for this journey
Task 1b:
Sketch an estimate of the distance time graph for your journey to school or work Describe how various features of the journey are represented on the graph

4. 6 Overtaking
The Highway code states that on an open road, in good conditions, a two second gap between cars should be sufficient.
Task:
Find the passing distance needed for a car to safely overtake a lorry moving at a steady speed of 50 mph.
Sketch a distance time graph (and velocity time graph) showing the car and lorry as the overtake happens
Extension:
Consider the case where the car slows down to match the lorry’s speed then speeds up to overtake
Draw diagrams
Choose variables and assign constant values
Interpret your solution
Evaluate:
Test the assumptions and conclusions you have
made by finding the time you would take to cover
2 km at scouts pace
