A rescue capsule is pulled through two sections of a rough horizontal tunnel. The pulling force acts in the direction in which the capsule moves.
| Tunnel section | Pulling force in N | Distance moved in m |
|---|---|---|
| 1 | 1200 | 18 |
| 2 | 1600 | 12 |
Calculate the total work done by the pulling force as the capsule moves through both sections of the tunnel.
Explain why the temperature of the capsule increases as it moves through the tunnel.
