A car’s engine provides a driving force of $5000\ \text{N}$ on the car. Resistive forces $R$ also act on the car, as shown. The car has a mass of $800\ \text{kg}$ and an acceleration of $1.0\ \text{m s}^{-2}$. What is the value of $R$?
- A$800\ \text{N}$
- B$4200\ \text{N}$
- C$5800\ \text{N}$
- D$8000\ \text{N}$
