A solid cylinder of mass M = 27 kg, radius R = 0.29 m and uniformdensity is pivoted on a frictionless axle coaxial with its symmetryaxis. A particle of mass m = 4 kg and initial velocity 14 m/s(perpindicular to the cylinder's axis) flies too close to thecylinder's edge, collides with the cylinder and sticks to it.Before the collision, the cylinder was not rotating. What is its angular velocity after the collision?
