Find the change in the gravitational potentialenergy of cord

Reference no: EM13315107

A uniform cord of length 4.0 cm and mass 26 g is initially stuck to a ceiling. Later, it hangs vertically from the ceiling with only one end still stuck. What is the change in the gravitational potential energy of the cord with this change in orientation? (Hint: Consider a differential slice of the cord and then use integral calculus.)
