Two point masses m1 2 kg and m2 1 kg are connected by a, Ask an Expert

Academics

Two point masses m1 = 2 kg and m2 = 1 kg are connected by a thin massless rod of length L = 2 m and are freely rotating in space with angular velocity ?= 3 rad/s. What is the kinetic energy of this rotation (in J)? Hint: about what point will the system rotate if it is freely rotating?
