As shown in the figure below, 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 80 km/h at point C, determine (a) the speed at point B, (b) the magnitude of the total acceleration when t = 12 s. -100 m → 150 m •A
