The question, in short
Use a speed–time graph for a 17-second car journey, rising from 0 to 20 m/s in 10 s then constant, to find acceleration and total distance.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Part (a) · 1 mark
Find the car's acceleration over the first 10 seconds from the graph.
- 1Acceleration = gradient = 20 ÷ 10 = 2 m/s²
Answer2
Part (b) · 3 marks
Calculate the total distance the car travels during the whole 17 seconds.
- 1Distance = area under the graph
- 21/2 × 10 × 20 + 7 × 20 = 100 + 140
- 3= 240 m
