Question 4: a) The 1.5 m long mass of which is attached to the ceiling of the room at one end is negligible and a small object with a mass of 0.75 kg is hung on the free end of an inelastic rope. This object makes a circular motion at a speed of 25 rad / s, making an angle of 30° with the vertical. 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 with a length L = 2.0 m has one end denser than the other and the density is A = (0.42 kg/m) - (0.15 kg / m ^ 2) depending on the x, which indicates the distance from the dense end. It is given by x. The stick rotates around the axis that passes through the heavy end and is perpendicular to it in a period of T = 0.30 s. Find the rotational kinetic energy of the stick.
