A cart is constrained to move along a straight line. A varying net force along the direction of motion is exerted on the cart. The cart's velocity v as a function of time t is shown in the graph above. The five labeled points divide the graph into four sections.

4) For which segment does the cart move the greatest distance?

(A) AB

(B) BC

(C) CD

(D) DE

5) Which of the following correctly ranks the magnitude of the average

acceleration of the cart during the four sections of the graph?

(A) a_CD > a_AB > a_BC > a_DE

(B) a_BC > a_AB > a_CD > a_DE

(C) a_AB > a_BC > a_DE > a_CD

(D) a_CD > a_AB > a_DE > a_BC
