Distance from one floor to the next h =3.5 m

(a). Potential energy in her office P= mg * 0 = 0 J

Since her office as the zero potential energy

(b). Potential energy on the 59 th floor = mg ( 59 th floor -33 floor )

= mg * 26 floors

= mg * 26 h

= 55*9.8 * 26 * 3.5

= 49049 J

(c). Potential energy at strret level = mg ( 0 thfloor - 33 floor )

= mg * -33 floors

= mg * -33h

= 55*9.8 * -33 * 3.5

= - 62254.5J
