There is a crest in the road leading up to Red Gate HQ which has prompted a discussion on our forum about how fast someone would need to be traveling to ‘take off’ while passing over the crest. We decided that ‘taking off’ simply meant the tyres leaving the surface of the road for any amount of time.
A group of us went out and calculated that the crest has a radius of 30 meters. What is the minimum constant speed that a car would need to be travelling in order to ‘take off’ as it passes over the crest? Please post your answers and workings below in the comments section.
