A motorcyclist is riding a motorcycle around a roundabout of radius 63m at 85 km/h. The combined mass of the motorcyclist + motorcycle is 307 kg. (a) Show that the centripetal acceleration of the motor cyclist is 8.8ms-2. (b) If the tyres are capable of providing a maximum frictional force of 2.00x10³N toward the centre of the roundabout, will the motor cyclist be able to take the curve without slowing down? Justify your answer. (c) What is the maximum speed that the motorcyclist could take this curve at? Give your answer in km/h.
