Question 36
FThe Figure shows the thinking distance and the braking distance for a car at five different speeds.
The driver, the car and the road conditions are the same for each speed.
Figure
a.[1]
Use the Figure to determine the stopping distance of the car at 20 m/s.
b.[2]
Use the Figure to calculate the reaction time of the driver.
c.[3]
Describe how the thinking distance, the braking distance and the stopping distance change when the speed of the car doubles from 10 m/s to 20 m/s.
Use data from the Figure in your answer.
d.[2]
A student says:
'The stopping distance at 30 m/s is three times the stopping distance at 10 m/s.'
Explain whether the student is correct.
