Find the external force on the block before it is removed

Reference no: EM13672390

The force constant of a spring is 500 N/m and the unscratched length is 0.64 meter. A 1.6 kilogram block is suspended from the spring. An external force slowly pulls the block down, until the spring has been stretched to a length of 0.77 meter. The external force is then removed, and the block rises. In this situation, find the external force on the block before it is removed?
