Understanding the Concepts

* Work: Work is done when a force causes an object to move a certain distance. It is calculated as: Work (W) = Force (F) × Distance (d)

* Joules: The unit of work is the joule (J).

* Newtons: The unit of force is the newton (N).

Solving the Problem

1. We know:

* Force (F) = 100 N

* Work (W) = 150 J

2. We need to find: Distance (d)

3. Using the formula: W = F × d

4. Rearranging the formula to solve for distance: d = W / F

5. Substituting the values: d = 150 J / 100 N = 1.5 meters

Answer: The rock was lifted 1.5 meters.
