Question

Supposed that you are an on-the-job trainee in a private investigating company tasked to
investigate a “hit and run” case. The alleged suspect was captured by a CCTV camera
driving a road leading to the place of incident. The suspect denied the allegation, saying
that he was driving very slowly with a constant speed. Because of the short time
difference when he was caught by the camera and when the accident happened, he insisted
that it wasimpossible that he would already be at the place when the crime took place. But
when you are viewing the CCTV footage, you noticed that his car has left oil spots on the
road. When you checked the spots on the site of the accident, you found out that they are
still evident. So, you began to wonder if the spots can be used to investigate the motion of
the car driven by the suspect and check whether he was telling the truth or not.
Examine the distances between the dots in the tape chart presented below:

1. How will you compare the distances between the dots?
2. What does the tape chart tell you about the speed of the car?
3. Create a motion graph based on the tape chart.
4. Analyze the motion graph and compare it to the information presented in the tape
chart.
5. Based on your investigation (tape chart and motion graph),prove whether the
suspect is telling the truth or not?
