Solve the problem.A simple exercise machine can be constructed by mounting a stiff spring securely to a wall and attaching a "T" handle to the free end of the spring. The arms can be exercised simply by pulling the "T" handle towards the torso. For a particular spring, the stretch distance is related to the work exerted by the equationx
= 
,where W is the work exerted in joules and x is the stretch distance in cm. How far will you stretch the spring if you exert 640 joules of work? Round your answer to three decimal places.
