When a cart rolls up a ramp, reaches it highest point, then rollsback down we expect the slope of the position curve when it reachesthe highest point to be
A. negative since it is now moving down the ramp
B. positive or negative depending which way the cart and the motiondetector are placed
C. zero since the velocity has to go to zero at a turningpoint
D. positive since it was moving up the ramp

Consider the velocity vs. time graph of a person in an elevator shown in Figure 2.58. Suppose the elevator is initially at rest. It then accelerates for 3 seconds, maintains that velocity for 15 seconds, then decelerates for 5 seconds until it stops. The acceleration for the entire trip is not constant so we cannot use the equations of motion from Motion Equations for Constant Acceleration in One Dimension for the complete trip. (We could, however, use them in the three individual sections where acceleration is a constant.) Sketch graphs of (a) position vs. time and (b) acceleration vs. time for this trip.
