Question
![Part B
A clever engineer designs a "sprong" that obeys the
force law F = -q(x – xe), where xe is the
Find an expression for the potential energy of a stretched or compressed sprong.
equilibrium position of the end of the sprong and q is
the sprong constant. For simplicity, we'll let xe = 0 m.
Then F = - gx?.
Express your answer in terms of the variables g and x.
