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?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
