Homework Help: Just an easy problem of physics

  1. Jan 12, 2010 #1
    If we want to pull a block with a weight of 5N attached to a rope that is just able to resist 20N. What is the minimum force that we need to exert in order to not break the rope? xD

    Draw a free-body diagram on the block, write out Newton's second law, and solve!
