Kinematics of motion in a straight line — practice question

A car with mass $1200\text{ kg}$ travels in a straight line over level ground. The resistive force on the car is constant, with magnitude $960\text{ N}$. The engine of the car operates at a rate of $17\,280\text{ W}$. The car goes through points $A$ and $B$. During the journey from $A$ to $B$, its speed is constant at $V\text{ m s}^{-1}$. The moment the car arrives at $B$, the engine is turned off and from then on supplies no energy. The car keeps moving along the same straight line until it stops at $C$. The time for the car to go from $A$ to $C$ is $52.5\text{ s}$.
