15 Two workers load identical refrigerators into identical trucks by different methods. One worker has the refrigerator lifted upward onto the back of the truck, which is 1.5 m above the ground. The other worker uses a ramp to slide the refrigerator onto the back of the truck. The ramp is 5.0 m long, and raises the refrigerator 1.5 m above the ground. The amount of work done by both workers is the same: 1800 J. What are the magnitudes of the forces each worker must exert to load the refrigerators?

Question

What are the magnitudes of the forces each worker must exert to load the refrigerators?

**Problem 15:** Two workers load identical refrigerators into identical trucks using different methods. - The first worker lifts the refrigerator directly upward onto the back of the truck, which is 1.5 meters above the ground. - The second worker uses a ramp to slide the refrigerator onto the back of the truck. The ramp is 5.0 meters long and raises the refrigerator 1.5 meters above the ground. The work done by both workers is the same: 1800 joules. **Question:** What are the magnitudes of the forces each worker must exert to load the refrigerators?
