A person slides freely down a frictionless inclined plane while his bag falls down vertically from the same height. The final speeds of the man (VM) and the bag (VB) should be such that:

1. VM < VB
2. VM = VB
3. they depend on the masses
4. VM > VB

Correct answer: VM = VB

Solution

Both the man and the bag start from the same height, and their final speeds depend only on the height due to conservation of energy. Since the plane is frictionless, the final speeds will be equal.
