A motorist starts from rest at point A on a circular entrance ramp when t-0, increases the speed of her automobile at a constant rate and enters the highway at point B. Knowing that her speed continues to increase at the same rate until it reaches 61.8 mph at point C, determine the magnitude of the normal acceleration (ft/s¹) at t=11s. Round off only on the final answer expressed in 3 decimal places. B -300 ft C
