Question in description (please answer)

A car of mass 1.5 tonnes is driving up a hill, the hill makes an angle of 10 degrees to the horizontal, at a constant 30km/h. Neglecting any friction, what is the power required from the engine to drive the car up the hill under these conditions?
just want the equation for it and answer please. i think its the kinetic energy equation.
KE= 1/2 X M X V^2 
but just want to be sure
thank you

Power = Force * speed
         = Mg Sin (Theta )* speed
        where Theta = 10 degree
Change to proper units and get the answer
tonnes to kg and km/hr to m/s
