The answer for sub question A) calculate the percent uncertainty in the distance is 0.059%.
The answer for sub question B) calculate the uncertainty in the elapsed time is 9,012 s
The answer for sub question C) what is the average speed in meters per second is 4.681 m/s
The answer for sub question D) what is the uncertainty in the average speed is 0.0032 m/s
How are the answers calculated?
To calculate the percentage of uncertainty of distance we have uncertainty = 25 m and distance = 42.188 km which is 42188 m.
Now [tex]\frac{25}{42188}[/tex] x 100% = 0.059%
To calculate time elapsed, we have the following data:
2hr which is 7200 s, 30 min which is 1800 s and 12 s
Adding these all up, we get 9012 s.
The average speed in m/s is calculated by 42188 m/ 9012 s = 4.681 m/s
The uncertainty in average speed is calculated by 4.681 m/s x [tex]\frac{0.059 + 0.01}{100}[/tex]
= 0.0032 m/s
