A winch moves a maintenance pod along a straight underground tunnel in two sections. In each section, the pulling force acts in the direction the pod moves.
The total work done by the winch is 1.08 MJ1.08\ \text{MJ}1.08 MJ.
| Section | Pulling force | Distance moved |
|---|---|---|
| A | 2.4 kN2.4\ \text{kN}2.4 kN | 150 m |
| B | 1.8 kN1.8\ \text{kN}1.8 kN | unknown |
Calculate the distance the maintenance pod moves in section B.
