E4.A rope applies a horizontal force of 280.0 N to pull a crate a distance of 22 m across the floor. A frictional force of 55.0 opposes this motion. What is the work done by the force applied by the rope? What is the work done by the frictional force? What is the total work done on the crate? E5.A force of 130 N is used to drag a crate 4 m across a floor. The force is directed at an angle upward from the crate so that the vertical component of the force is 120 N and the horizontal component is 50 N, as shown in the diagram. What is the work done by the horizontal component of the force? What is the work done by the vertical component of the force? What is the total work done by the 130-N force? 120 N! 50 N

**Graph/Diagram Description:**

The diagram associated with E5 illustrates a force vector separated into its vertical component (120 N) and horizontal component (50 N). The vector angle is not specified, but the depiction shows how the overall force vector divides into these components acting on the crate.
