So I have a simple lever that is connected to an extension spring. When the extension spring is exteneded it applies a force of 40lbs on the lever. The lever is 3 feet long and the pivot point is 1 foot from the top and 2 foot from the bottom. The lever weighs 2.1 lbs and has a 3lb weight attached to the bottom. Can anyone help me figure out what the speed is at the bottom of the arm. I attached a picture to this thread. The speed I need is the point when the lever is at rest as seen in the diagram.
