The 10-kg double wheel with radius of gyration of 125 mm about O is connected to the spring of stiffness k = 600 N/m by a cord which is wrapped securely around the inner hub. If the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center O during the ensuing motion. The wheel rolls without slipping.
