The rock was lifted 1.5 meters.

Explanation:

We can use the energy equation W = Fd and substitute the given values. W = 150 J and F = 100N. Joules can be converted into Newton * meters, so the entire equation can be written as 150 N * m = 100N * d. Dividing by 100N on both sides results in the expression 1.5m = d. Thus, d, or distance equals 1.5 meters.
