4. Two carts roll toward each other on a level table. The vectors represent the velocities of the carts just before and just after they collide. B B Before After a. Draw and label a vector for each cart to represent the change in velocity from before to after the collision. Make the magnitude and direction of your vectors consistent with the vectors drawn above. Show your work. b. How does the direction of the average acceleration of cart A compare to the direction of the average acceleration of cart B over the time interval shown? Explain. c. For the time interval shown, is the magnitude of the average acceleration of cart A greater then. less than, or equal to the magnitude of the average acceleration of cart BY Explain
