When making a turn on a bicycle you must lean at the correct angle. To be stable, the line of action of the force exerted by the ground must pass through the centre of gravity as shown in Figure 1. FN 1 10 F g Ff The force exerted by the ground may be resolved into two components, the friction parallel to the ground, and the vertical normal force F = F + F - Calculate for an r = 25.0 m turn at 9.00 m/s. Enter your answer in degrees. N
