The 15.0-kg double wheel with radius of gyration of 100 mm about O is connected to the spring of stiffness k = 460 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 310 mm, calculate the maximum velocity v_{max} of its center O during the ensuing motion[ [m/s]. The wheel rolls without slipping.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
