The 2012 Lamborghini Muricielago has a 640 horsepower engine, drag coefficient of .33, and a cross sectional area of 2.35 m^2.
1. Calculate the top speed (at sea level) of the vehicle if the only external forces on the vehicle are the friction between the tires and the road and the aerodynamic drag which is given by
D= (1/2)pv^2C(d)A Where p= air density, C(d)=drag coefficient, and A= cross sectional area. The published top speed is 205 mph. What power losses are not accounted for?
2. For the same vehicle, if I reduce by 50%, what is the percentage drop in top speed?
