A driver finds that her car will descend the slope θ1 = 3° at a certain constant speed with no brakes or throttle required. The slope decreases fairly abruptly to θ2 at point A. If the driver takes no action but continues to coast, determine the acceleration α of the car just after it passes point A for the conditions

(a) θ2 = 1.5°

(b) θ2 = 0°
