Jane is dragging a 1.2 lbf suitcase across the floor by tying a rope to it and applying a force at an angle of 7.4 degree above the floor. She found that it takes 1.6 N of force to keep it moving at a constant velocity. What is the coefficient of dynamic friction between the floor and the box? Andrew is moving a W=3.4 lbs box by pushing the box forward and down with a force of F=4.2 N. He...
