You are riding in a thrill ride at the State Fair, where you are spun around in a large, horizontal circle at the end of a long metal arm. If you are traveling with a constant speed of 15 m/s and you feel an acceleration of twice the acceleration due to gravity, what is the length (approximately) of the arm?
