Lindsay is going out for a bike ride. She loves to ride along the Wabash river. Lindsay weighs approximately 70 kg, and her very pink bicycle weighs 4 kg. The total weight is supported equally by the two wheels. The bicycle tires are 0.018 m wide, and have been carefully inflated to a total gauge pressure of 7.95 x 105 Pa. Determine how much of each tire (i. e., the length) is in contact with the ground at any time.
