An airplane passenger carries a 260 N suitcase up the stairs, a displacement of 3.80 m vertically, and 4.30 m horizontally.

(a) How much work does the passenger do?
(b) The same passenger carries the same suitcase back down the same stairs. How much work does the passenger do now?

  • Physics -

    work= mg*height
    this time,gravity does work on suitcase,so it is negative.

  • Physics -

    So how am I supposed to use the heights given from the problem? Subtract 4.30 m from 3.80 m?
