8   3. A girl is cycling round a circular track. The girl and her bicycle have a combined mass of 55 kg. The coefficient of friction between the track surface and the tyres of the bicycle is μ. The track is banked at an angle of 15° to the horizontal. The girl and her bicycle are modelled as a particle moving in a horizontal circle of radius 50 m The minimum speed at which the girl can cycle round this circle without slipping is 4.5 m s–1 Using the model, find the value of μ.
