Yupp.
See the mass of the car was 600kg and the acceleration was 1.4 and the Power given to you was 22.5 kW. and v=18
D - R = ma
=> D = R + ma
=> R = D - ma
=> R = P/v - ma
Blah blah... right?

And then you substitute that into something else and wala! You get the answer.
I guess I typed something wrong in the calculator then. -___-
