Question

1.3.2 quiz: organizing and analyzing experimental results
what is the best inference for the speed of the car after 17 seconds?
a. 28 m/s
b. 30 m/s
c. 26 m/s
d. 29 m/s

Explanation:

Step1: Observe the graph trend

The speed - time graph shows a gradually increasing trend and starts to level off around 20 - 25 seconds.

Step2: Locate 17 seconds on the x - axis

We note the position of 17 seconds on the time axis.

Step3: Estimate the speed value

By looking at the curve, we can see that the speed at 17 seconds is between 25 m/s and 28 m/s. It is closer to 26 m/s.

Answer:

C. 26 m/s
