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 69.94 mph at point C, determine themagnitude of the tangential acceleration (ft/s²) from A to B.

Round off only on the final answer expressed in 3 decimal places.
