If the bicycle and rider have a total weight of 180 lb, determine the resultant normal force acting on the bicycle when it is at point A while it is freely coasting at v_A = 6 ft/s. Also, calculate the increase in the bicyclist’s speed at this point. Neglect the resistance due to the wind and the size of the bicycle and rider.
