Practice objective / multiple choice question 1 from the 2017 Igcse Model Questions Vol1 Physics examination.
A car starts from rest and accelerates uniformly. After 5 s its speed is 20 m s\(^{-1}\). It continues with the same acceleration and travels a total distance of 250 m from the start to point A. At point A the driver applies a uniform braking force that brings the car to rest over the next 30 m. What is the magnitude of the deceleration during the braking phase? Give your answer in \(\text{m s}^{-2}\) to three significant figures.
