A thin-walled hollow cylinder is rolling on a surface. What fraction of its total kinetic energy is in the form of rotational kinetic energy about the center of mass? The answer is not 2/5.
what is the kinetic energy of a ball with a mass of 5 kg rolling at 10 m/s
You wind a string around the outer rim of a solid disc with a radius of 10.0 cm and a mass of 2.80 kg. The disc sits flat on a frictionless horizontal surface. You pull on the string with a force of 10.0 N for 3.00 s. Note: In this problem the object is not rolling without slipping, so you cannot use v = ωr or a = αr. a) What is the final kinetic energy of the disc? This...
