A truck travels 60 mph on a smooth hosizontal road. The frontal area of the truck is 100 square feet. The air temperature is 60 degrees F and standard atmospheric conditions exist. The drag coefficient is 0.62. A.) Determine the power output required to maintain constant speed with no wind. B.) Assume constant power, determine the velocity of the trick if traveling against a 30 mph wind, C.) traveling with a 30 mph wind.
