A car of mass $1150\text{ kg}$ travels up a straight hill inclined at $1.2^\circ$ to the horizontal. The resistance to motion of the car is $975\text{ N}$ . Find the acceleration of the car at an instant when it is moving with speed $16\text{ m s}^{-1}$ and the engine is working at a power of $35\text{ kW}$ .
