1 x-1 D WVertical Velocity O - Time Two students, student 1 and student 2, are discussing the graph shown above, which shows the vertical component of the velocity of the box from when it leaves the ramp to immediately before it hits the floor. The students make the following statements. Student 1: This graph shows that the vertical acceleration of the box is constant, and that the box's speed decreases for the entire time shown. Student 2: The area between the graph and the time axis is the box's vertical displacement, but the graph is incorrect because the positive displacement should be equal to the negative displacement.
