In each test run, a rail vehicle starts from rest and moves in the direction of the constant resultant force. The table shows the force and distance moved in each run.
| Test run | Resultant force in N\mathrm{N}N | Distance in m\mathrm{m}m |
|---|---|---|
| A | 18 000 | 1300 |
| B | 24 000 | 1050 |
| C | 30 000 | 800 |
Use calculations to show which test run gives the greatest increase in the vehicle's kinetic energy store.
