An airport tug is towing a baggage train at 8.0 m/s. The driver's reaction time is 0.75 s. In a test, the stopping distance of the tug at this speed is 22 m. Later, the same driver drives the tug at 4.0 m/s with the same load and the same braking force.
Calculate the stopping distance of the tug at 4.0 m/s.
126 exam-style questions on Edexcel GCSE Physics 2.5 Stopping and braking distances, covering 2.5.1 Stopping distance and reaction time, 2.5.2 Factors affecting stopping distance, 2.5.3 Dangers of large decelerations, and 2.5.4 Braking distance and initial speed. Each one has a worked solution and a mark scheme showing where the marks go.
