Question

a students motion is captured using a motion detector and displayed on the graph shown. use the graph to answer the following questions. right is defined as positive. answers have a 5% tolerance to allow for estimation. describe the direction of travel: describe the motion: what is the distance traveled? what is the final speed?

Explanation:

Step1: Analyze position - time graph

The position remains constant at 300 m over time from 0 s to 18 s.

Step2: Determine direction of travel

Since position doesn't change, there is no displacement. So, no net direction of travel.

Step3: Describe the motion

The motion is stationary as position is constant.

Step4: Calculate distance traveled

As there is no change in position, distance traveled \(d = 0\) m.

Step5: Calculate final speed

Speed \(v=\frac{\Delta x}{\Delta t}\), with \(\Delta x = 0\) (no change in position), so \(v = 0\) m/s.

Answer:

Describe the direction of travel: No net direction
Describe the motion: Stationary
What is the distance traveled? 0 m
What is the final speed? 0 m/s
