A stuntswoman drives a bike over the top of a hill, the cross section of which can be approximated by a circle of some radius R; as shown in the diagram. She finds that, at maximum, she can drive the bike at a constant speed 120km/hr without the bike flying off the top of the hill. Use this information to find R in meters. (You may use g= 9.81m/s')
