A Porsche 944 Turbo has a rated engine power of 217 hp (161882 W). 70% of the power is lost in the drive train, and 30% reaches the wheels. The total mass of the car & driver is 1480 kg, and two thirds of the weight is over the drive wheels.(adsbygoogle = window.adsbygoogle || []).push({});

What is the max acceleration if the coefficient of static friction is 1?

(2/3)(1480 kg)(9.80)*1= 9669.33 N Force of static friction

Set this = to mtotal* a 9669.33N=(1480)a a= 6.53 m/s^2

What is the speed of the Porsche at max power output?

P=Fv

F= 9669.33 N P= (161882 W) * (.70) = 113317.4 W

113317.4= (9669.33 N)v

v=11.72 m/s which is about 26.2 mph Does this seem fast enough???
