Assuming your tests were performed correctly and you obtained accurate results, how can you explain if your analysis of the unknown fiber yields results that either do not match the results for your 6 standards, or match results for multiple standards?

scientific laws are the result of testing theories and proving them to be facts.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
