The rigid object shown below consists of three balls and three connecting rods, with M = 1.6 kg, L = 0.6 m and 0 = 30°. The balls may be treated as particles, and the connecting rods have negligible mass. Determine the rotational kinetic energy of the object if it has an angular speed of w = 1.2 rad/s about %3D (a) an axis that passes through point P and is perpendicular to the plane of the figure, coming out towards your eyes , and (b) an axis that passes through point P and lies on the rod of length 2L in the plane of the figure. (Hint: the distance from a particle to the axis of rotation is the length of the line connecting the particle to the axis that is perpendicular to the axis.) 2M 2L 2M
