Reference no: EM131705360

At this point in the problem set, you are probably shaking your head. So, let's calculate the rotational energy in a head shake. Approximate the head as a sphere with radius of 7.662 cm and a mass of 5.87 kg. Assume it takes 0.353 s to rotate a quarter-turn around the neck. Express your answer in J.
