Calculate the rotational kinetic energy of a sledgehammer being swung around its end at an angular speed of ω=2.901 rad/s. Model the sledgehammer as a long, thin rod with length L = 1.099 m and mass m = 1.320 kg, with a small, massive head with M = mass 5.79 kg on the end. You can model the small, massive head as a point particle, contributing ML2 to the moment of inertia. Express your answer in Joules.
