Q. A biology student rides her bike around a corner of radius 24 meter at a steady speed of 8.3 m/sec. The combined mass of the student and the bike is 87 kg. The coefficent of static friction between the bike and the road is μs = 0.39. What is the magnitude of the total force between the bike tire and the road? Is it F = umg + mv^2 / R [ 'u' here is the static firction 0.39 ] Is this right.
