a 840 N crate rests on the floor how much work is required to move it at constant speed 5.5m along the floor against a friction force 180 N?

  • physics -

    The force required to move the crate at constant speed should just be greater than the frictional force.

    F (ext.)= 180 N
    Work done = F*s = 180*5.5 = 990 J
