Question in description (please answer)

Question

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

Answer 1

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
