The problem statement, all variables and given/known data Energy is to be stored in a flywheel in the shape of a uniform solid disk with a radius of = 1.30m and a mass of 66.0kg . To prevent structural failure of the flywheel, the maximum allowed radial acceleration of a point on its rim is 3600m/s² . What is the maximum kinetic energy that can be stored in the flywheel? The attempt at a solution I took I = 3/2MR² (at rim) where R = 2.6m Then K = 1/2 * I * ω², where ω² = a/R so K = (1/2)(3/2)(66kg)(2.6m)²(3600/2.6) = 463320J which is wrong.. The ans is 7.72x10^4 J can someone pls tell me where i gone wrong? Thanks!!
