The discussion revolves around calculating velocity using the formula v = sqrt(2*g*change in y), where the change in y is given as 12.10 cm with an associated standard error of ±0.06 cm. Participants are exploring how to incorporate the standard error into their velocity calculation.
The discussion is ongoing, with participants sharing different methods for incorporating standard error into the velocity calculation. There is no explicit consensus, but some guidance has been provided regarding the algebraic approximation for small errors.
Participants are working within the constraints of homework rules, which may limit the methods they can use to evaluate their answers. There is also uncertainty about the correct approach to handle the standard error in the context of the velocity formula.
That'll work. The algebraic way is to approximate sqrt(x + dx) = sqrt(x)sqrt(1+dx/x) as sqrt(x)(1+dx/2x) for small dx.JazzyJones said:i'm not sure if this was correct but, I plugged in the value with + then plugged in te value with -. Average the two values, and did + or - the difference between the two
