question 295

Multiple Choice

Rationalize the denominator. Assume that all variables represent nonnegative numbers and that the denominator is not
zero.
-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 equation x $$x = \sqrt { \frac { 2 W } { 85000 } }$$ 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 669 joules of work? Round your answer to three decimal places.

• A) 0.016 cm
• B) 0.089 cm
• C) 0.125 cm
• D) 0.134 cm
