A 2500-lb passenger vehicle originally traveling on a straight and level road gets onto a section of the road with a horizontal curve of radius = 850 ft. If the vehicle was originally traveling at 55 mi/h, determine: (a) the additional horsepower on the curve the vehicle must produce to maintain the original speed,
(b) the total resistance force on the vehicle as it traverses the horizontal curve, and
(c) the total horsepower.
Assume that the vehicle is traveling at sea level and has a front cross-sectional area of 30 ft2.
