4. Cassie steps outside to complete a long run and improve her cardiovascular strength. She is very fast! She brings along her little dog, who runs ahead of her, keeping a tension on the leash the entire time. The hardest part of her trip is when she climbs up a hill that is inclined at 25° above the vertical. While this is happening, her dog's leash makes an angle with the hill of 5º. Also, the wind is at Cassie's back and is moving horizontally. Draw a free-body diagram summarizing all the forces acting on Cassie during this difficult time on her run. Include angles to clarify the directions.
