A test pod travels along a winding subterranean track designed for vacuum-tube transportation research.
The maximum safety speed for the pod on this specific section of the track is 45 m/s45\text{ m/s}45 m/s. The length of the curved track between two consecutive monitoring sensors is 3.6 km3.6\text{ km}3.6 km.
Calculate the minimum time, in seconds, it takes the pod to travel between the two sensors without exceeding the maximum safety speed.
Explain why the average speed of the pod and the magnitude of its average velocity between these two sensors are different.
Practise AQA GCSE Physics Forces and motion with exam-style questions for Foundation and Higher tier. 83 questions covering Describing motion along a line, Forces, accelerations and Newton's Laws of motion, and Forces and braking, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
