Question
Chapter 2, Problem 1Q
To determine
Sketch a velocity-time graph with negative acceleration and give an example for such a motion.
Expert Solution & Answer
Answer to Problem 1Q
An object ejected from earth’s surface is an example for such a motion and the graph has been drawn.
Explanation of Solution
An object escapes from Earth’s surface to space with a high initial velocity will have the velocity is always positive, but the acceleration is always negative. Eventually the velocity will diminish resulting in negative acceleration. The velocity will never be zero in such cases.
The sketch for such a motion is given in figure 1.
Conclusion:
An object ejected from earth’s surface is an example for such a motion and the graph has been drawn.

A physics student at a track meet has a radar gun which she can use to measure the speeds of the runners. Shortly after the start of one race she measures that the speed of a runner is 1.57 m/s. When the runner is 11.2 meters farther along the track, she measures the runner’s speed to be 7.87 m/s. Determine the runner’s acceleration during this interval (assuming the runner’s acceleration is constant)?

- I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.arrow_forwardA student drives a moped along a straight road as described by the velocity–time graph as shown.
