1. The coefficient of friction between a block and the floor is 0.35. If a force of 20 N acting 35 degrees above the horizontal gives the block a constant velocity. Find the mass of the block. 2. 2. A force of 180 N is required to slide a loaded box along a horizontal floor. If the coefficient of friction between the box and the floor is 0.32, what is the mass of the box? 3. 3. A 30-kg box is allowed to slide on an inclined plane 30 degrees with the horizontal. If the coefficient of sliding friction is 0.80, what is the magnitude of the frictional force which slows down the box’s motion down the slide? 4. A 60-N toolbox is dragged horizontally at constant speed by a rope making an angle of 35 degrees with the floor. The tension in the rope is 40 N. (a) Determine the magnitude of the friction force and normal force. (b) What is the coefficient of friction?
