    A modern grand-prix racing car of mass mm is travelling on a flat track in a circular arc of radius RR with a speed vv. If the coefficient of static friction between the tyres and the track is μs\mu_{s}, then the magnitude of negative lift FLF_{L} acting downwards on the car is: (Assume forces on the four tyres are identical and g=g= acceleration due to gravity)
