This question has two parts.
19a) Student A is looking at a velocity-time graph. The graph shows a section that has a straight horizontal line segment. Student A says that this shows the object not moving since its acceleration is zero during this time. This is incorrect. Explain the student’s error.
19b) The graph represents an elevator stopped at the second floor to pick up passengers, then descending to the ground floor for them to exit, then returning to the second floor. The company that manufactures the elevator claims that, for safety
reasons, their elevators
always go down slower than
they go up. Is this claim
supported by the graph?
Why or why not?
