Energy is to be stored in a flywheel in the shape of a uniform solid disk with a radius of R = 1.16 m and a mass of 74.0 kg . To prevent structural failure of the flywheel, the maximum allowed radial acceleration of a point on its rim is 3490 m/s2. What is the maximum kinetic energy that can be stored in the flywheel?

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
