A vehicle of mass 2000 kg coasts along a horizontal track against a drag force Fd (in N) on the automobile given by the following Fd=kV^2 where k= 1.25 kg/m and V is the speed in m/s. Assume the force that the engine must exert is equal to the drag force. The power exerted by the engine is 75hp. What is the maximum steady speed (in mph)?
