A double radius pulley is attached to a wall by an axle of negligible friction and is initially at rest. Two vertical forces, both with magnitude ?1P = ?2P =15 N, are applied at the radii ?1 =0.5 m and ?2 =1 m as shown. Determine the kinetic energy of the pulley after it has undergone one full rotation.
