A) Its 1.5 m long mass, one end of which is connected to the ceiling of the room, is negligible and flexible a small object weighing 0.75 kg is hung on the free end of a rope. This object will make a 30° angle with the vertical it makes a circular motion with a speed of 25 rad /s.

a1) What is the rotational kinetic energy of this object?

a2) What is the rotational kinetic energy of the object if the angle is 60°?

B) A thick stick of length L = 2.0 m is denser at one end than the other, and the density is λ = (0.42 kg /m) - (0.15 kg /m²) depending on the distance x is given by x. Passing through the heavy end of the stick and rotates around the axis perpendicular to it with a period of T = 0.30 s.

Find the rotational kinetic energy of the stick.
