A bow is drawn so that it has 40 J of potential energy. If we ignore air resistance then fired, the arrow will ideally have a kinetic energy of 1.more than 40 J
2.Less than 40 J
3.40 J

The 10-kg double wheel with radius of gyration of 125mm 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
