A car moves along a road. The force exerted on the car by the engine is $800\,\text{N}$. The car’s motion depends on the magnitude of the total resistive force $R$. Which row indicates the car’s motion for the stated value of $R$?
- A$R = 500\,\text{N}$, deceleration
- B$R = 800\,\text{N}$, acceleration
- C$R = 900\,\text{N}$, deceleration
- D$R = 1000\,\text{N}$, acceleration
