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.

    A glider of length moves through a stationary photogate on an air track. A photogate (Fig. P2.19) is a device that measures the time interval td during which the glider blocks a beam of infrared light passing across the photogate. The ratio vd = /td is the average velocity of the glider over this part of its motion. Suppose the glider moves with constant acceleration. (a) Argue for or against the idea that vd is equal to the instantaneous velocity of the glider when it is halfway through the photogate in space. (b) Argue for or against the idea that vd is equal to the instantaneous velocity of the glider when it is halfway through the photogate in time. Figure P2.19
