a mule uses a rope to pull a box that weighs 3.0x10^2N across a level surface with a constant velocity. the rope makes an angle of 30.0 degrees above the horizontal and the tension in the rope is 1.0x10^2N. what is the normal force on the floor on the box?

  • physics -

    300 N (weight) - 100 N*sin 30 = 250 N

  • physics -

    250
