Archimedes Principle states that an object will float if the weight of the water it displaces is equal or greater than the weight of the object. Weight is multiplied by the due to and mass is multiplied by . So after equating the two weights, the constants of and divide out. In practice, this means an object will float if its is equal to or than the of the .

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?
