A biology student rides her bike around a corner of radius 25 meter at a steady speed of 8.2 m/sec. The combined mass of the student and the bike is 87 kg. The coefficient of static friction between the bike and the road is ?s = 0.37.
a) If she is not skidding, what is the magnitude of the force of friction on her bike from the road?
b) What is the minimum value the coefficient of static friction can have before the bike tire will skid?
c) What is the magnitude of the total force between the bike tire and the road?
