Aforce of 80 n is exerted on an object on a frictionless surface for a distance of 4 meters. if the object has a mass of 10 kg, calculate its velocity. v = 64 m/s 16 m/s 8 m/s 4 m/s

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
