Need help finding % difference last question on page. I kind of have an idea of how to set up but my answer isn’t making sense.

It seem that in order to solve the above we have to know what is the value of N. What is the value of N??

What concepts of General Physics 1 does this picture have?

3. Using the instruments from problem 1, you can take the following measurements for the distance a toy car travels in 10 seconds during each of  5 trials: 157 cm, 175 cm, 162 cm, 168 cm, 187 cm. What are the percent uncertainties of the distance and time measurements? Which of the two measurements is the most uncertain? 4. Calculate the average speed of the toy car. Use the weakest link rule to determine the uncertainty in the speed.
