Part 3: Problem Set 1. An object is pulled by a rope and dragged to the right 12 meters across a rough surface. The tension in the rope is 105 N and the rope makes an angle of 35 degrees with the horizontal. The rough surface exerts a constant frictional force of 50 N as the object is dragged. 105 N 12 meters a) Find the total amount of work done on the object. Consider the following forces: tension, friction, gravity and normal. b) Use the work energy theorem to find the block's change in kinetic energy.
