An old English nursery rhyme starts off "Jack and Jill went up the hill to fetch a pail of water". If the hill is 10 m high and Jack weighs 700 N, how much work in Joules did Jack need to do to get to the top of the hill?

  • PHUSICS - ,

    W = Fd = 700 * 10

    assuming a weightless bucket :-)
    or, Jill carried it.


    7000N = 7000J
