Question

Aa solid cylinder of mass 10 kg and radius is 0.5 rotates about its Axis with angular speed of 100rad/ s . what is a kinetic energy of the rotation cylinder what is the magnitude of angular momentum of the cylinder about its axis

Answer 1

Answer:

Mass of the cylinder, m = 20 kg Angular speed, ω = 100 rad s–1 Radius of the cylinder, r = 0.25 m The moment of inertia of the solid cylinder
