Power and velocity (P = Fv)

A car of mass 900 kg is driving up a straight road inclined at 8.0° to the horizontal. At an instant when its speed is 15 m s⁻¹, it has an acceleration of 1.2 m s⁻² up the slope. Neglecting resistive forces and taking $g = 9.81\,\text{m s}^{-2}$, what is the power developed by the engine at that instant?
