Chino is cycling along a flat road with a speed of 15 m/s when he starts to SPEED UP just before entering the ascending section A-B. He changes his speed at a constant rate until his speed at B becomes 21 m/s. Section A-B has a constant curvature of 400 m. 400 m 400 m A 1. Which of the following accelerations are directed to the right? I. The total acceleration just before passing point A. II. The total acceleration just after passing point A. III. The tangential acceleration just after point A. IV. The normal acceleration just after point A.
