Homework Statement
A turntable of radius "r" is spinning counterclockwise at an initial rate of ω. at t=0, its rotation rate begins to slow at a steady pace. the rotation finally stops at t=T. At what time is ωt^2 maximum. Express your answer in terms of T.
7.0711 instead of 10, and i didn't expect that to be a fixed relationship but it seems to be. so for ω^2 to be one half of that ω=.70711ω though i expect that there is a neater form of that
i'm honestly not sure how to determine what ω needs to be nor when it will get there. ω^2 obviously has to be half as large but I'm not sure where to go from there
