Is this calculation correct for v = 2πfA ?? 1. The problem statement, all variables and given/known data Prove that maximum speed of a mass on a spring is given by 2πfA Ac = Centripetal acceleration r = radius v = velocity f = frequency π = pi 2. Relevant equations Ac = (v^2)/r Ac = 4(π^2)r(f^2) 3. The attempt at a solution If Ac = (v^2)/r and Ac = 4(π^2)r(f^2) then (v^2)/r = 4(π^2)r(f^2) so v^2 = 4(π^2)(r^2)(f^2) and v = 2πrf Just wondering if there is something wrong with this calculation?
