Find work of an object at constant velocity

  1. Jan 29, 2014 #1
    I lower an object at constant velocity.
    What is the sign of the total work done on the block?
    What is the sign of the work done by gravity on the block?
    What is the sign of the work done by my hand on the block?
    What is the sign of the work done by the block on my hand?


    I know that work = Force * distance.

    Any help is much appreciated!
