Chapter 2, Problem 1CQ
A person gets in an elevator on the ground floor and rides it to the top floor of a building. Sketch a velocity-versus-time graph for this motion.
Expert Solution & Answer
To determine
To draw: The velocity-versus-time graph.
Answer to Problem 1CQ
The velocity-versus-time graph is drawn.
Explanation of Solution
Given data:
A person gets in an elevator on the ground floor and rides it to the top floor of a building.
Explanation:
Normally when the elevator starts to function, initially the speed or velocity will be low and then gradually increases its speed. In the middle period of the elevator functioning, the speed becomes constant and at end period speed slows down and comes to rest.
The velocity-versus-time graph for the above scenario is shown in Figure 1.
Initially graph starts from zero, gradually increases. During middle period velocity remains constant showing horizontal line in the graph. During end period there will be gradual decrease and end at zero in the graph.
Conclusion:
Hence, the velocity-versus-time graph is drawn.

Yesterday you walked 20 meters to the right from your house to the bus stop, which took
you 20 seconds. You waited at the bus stop for 1 minute before realizing you forgot your
Mathematics homework at home. You ran back to your house in 5 seconds. It took you 10
seconds to find your homework, and then you ran back to the bus stop in 5 seconds just in
time to catch the bus. What was your average velocity for the entire period of motion?
