Homework Statement
You have determined the acceleration [itex]a_{i}[/itex] of an object in free fall for i = 1 to n different time intervals. What is the algebraic expression for the uncertainty [itex]σ_{a,avg}[/itex] in [itex]a_{avg}[/itex]? (Use any variable or symbol stated above as necessary.)
The answer box is formatted as such: [itex]σ_{a,avg}[/itex] = [itex]\sqrt{\sum^{i=1}_{n}}[/itex]
and I have to fill in the space after the summation under the square root.
No variables or symbols were specifically given for the problem outside of the ones in the question, but I had written the formula for average acceleration previously (in the relevant equations section) that may have variables I can use.
Homework Equations
[itex]a_{avg}[/itex] = [itex]\frac{v_{23} - v_{12}}{t_{23} - t_{12}}[/itex]
The Attempt at a Solution
I honestly have no clue where to begin. I don't really have much knowledge of uncertainty calculations and so I am pretty lost here. I tried one method first that I realized is incorrect.
Any help would be extremely appreciated.
