The energy E of a rotating object varies directly as the product of its angular mass I and angular velocity w, and inversely as the square of its radius r. The energy E is 100 J for a angular mass of 2kg m^2, radius 0.5m and angular velocity 10 rad per second. Find the energy for the angular mass 1 kgm^2, radius 0.3 m and angular velocity 5 rad per second.
