Homework Statement

You are hired as a physicist in a team of Formula 1. Your driver is driving in the
Germany Grand Prix on the Hockenheim track. After the test session taken in sunny day
you and the driver discuss about the sharpest turn on the track. He tells you that when
driving at 90 km/h he could hardly hold the track. During the Grand Prix, just ten laps to
go, it starts to rain. The driver decides to continue on the same tyres. You have to
calculate the new maximal safe speed at this turn. The tyre-to-road static friction
coefficient is 0.8 for dry and 0.5 for wet road conditions. What would be the speed if the
turn were profiled at an angle of 7º?
