A 3590-lb car travels up the 7-percent incline shown. The car is subjected to a 45-lb aerodynamic drag force and a 38-lb force due to all other factors such as rolling resistance. Determine the power output required at a speed of 65 mi/hr if (a) the speed is constant and (b) the speed is increasing at the rate of 0.08g. 65 mi/hr V = 7 100 Answers: hp (a) Constant speed: P = (b) Increase in speed is 0.08g: P= i hp
