A lorry moves on a straight, level road. The lorry has a constant driving force of $80\,\text{kN}$, while the total resistive force is $20\,\text{kN}$. Which row states how the lorry is moving and gives the resultant force on it?
- Aacceleration, $60\,\text{kN}$
- Bacceleration, $100\,\text{kN}$
- Cdeceleration, $60\,\text{kN}$
- Ddeceleration, $100\,\text{kN}$
