Combination rotates around rotationaxis with angular speed

Reference no: EM13653047

In the figure, two particles, each with mass m = 0.82 kg,are fastened to each other, and to a rotation axis at O,by two thin rods, each with length d = 5.7 cm and massM = 1.4 kg. The combination rotates around the rotationaxis with angular speed ω = 0.26 rad/s. Measuredabout O, what is the combination's kinetic energy?
