    Rotating Falling Object: Calculating Force and Energy at Impact

    The object doesn't go airborne and rotate around the bottom. :) I thought that there is just one force on the object (except the force that initiated the movement) during the process that's the acceleration of gravity. If the object is standing the acceleration will be discharged on the...

    Rotating Falling Object: Calculating Force and Energy at Impact

    Fd=mgh=(mv^2)/2 is this right? What do you mean with "airborne", do you mean if we consider the air friction?? (I'm sorry, I'm an italian exchange student...) The centripetal acceleration would decrease from 9,81m/s^2 to 0, right? And at the same time the tangent acceleration would do the...

    Rotating Falling Object: Calculating Force and Energy at Impact

    I'm sorry I didn't give enough information, we should consider the mass uniformly and the base does not slip. About the force being meaningless I think it's the biggest error I made (try to find a force) but still I don't know how to calculate the velocity of the top I need for the momentum. Is...

    Rotating Falling Object: Calculating Force and Energy at Impact

    Homework Statement A wet floor sign is pushed on the top and it starts falling. Just before hitting the floor the upper point of the sign sign hit a foot. The weight of the sign is 5 pounds (2.27 Kg or 22.24 N). The sign is 2 feet tall (0.61 m). Homework Equations With what force and energy...
