Homework Help: A Work problem

  1. Apr 15, 2007 #1
    This questions asks what is the work done by the tension in the cable. And, the book answered that it is equal to the work done by the gravity.
    But shouldn't it be more than the work done by the gravity? (because there is also a horizontal displacement)

    I can't see your attachment yet, what is the direction of the force? So what is [itex]\vec{F} \cdot \vec{d}[/itex] ?
