2.4.19. [Level 2] A bicyclist comes around a decreasing-radius turn and maintains a constant speed of 20 mph. The radius of curvature varies as r= a +bs2, where s indicates motion along the curve expressed in feet (a = 50 ft and b = -0.0025 ft ¹). How long will it be until the bicycle slips if the maximum acceleration it can sustain without slip is 28 ft /s²? -Bicyclist
