Problem
Three identical point masses of 0.50kg occupy the vertices of an equilateral triangle of side 0.30m. The triangle rotates at a constant angular speed of 5.0rad/s about an axis perpendicular to its plane through its center of mass, while the center of mass translates at 2.0m/s in the plane. Determine (a) the translational kinetic energy of the system and (b) its rotational kinetic energy about the center of mass. Report both values.
