A solid cylinder of mass M = 30 kg, radius R = 0.19 m and uniform density is pivoted on a frictionless axle coaxial with its symmetry axis. A particle of mass m = 4.5 kg and initial velocity v0 = 17 m/s (perpendicular to the cylinder’s axis) flies too close to the cylinder’s edge, collides with the cylinder and sticks to it. Before the collision, the cylinder was not rotating.

What is the magnitude of its angular velocity after the collision?

Answer in units of rad/s.

The Sun does emit xrays. You'd have to place your sensor above the Earth's atmosphere because it blocks out nearly all x-rays. This is why we have the Chandra observatory ( http://chandra.harvard.edu/xray_astro/absorption.html )
