Question:
Emmanuc Macron was driving on Miami highway a CIMC trying to overtake Michel Aoun was in the same direction with a truck, The speed of vehicles was 60 and 45 mih respectively. On the other direction Angela Merkel driving her Mercedes 30OL, with a speed of 90 mi/h. Calculate the horsepower needs to be developed to overtaking, on an uprade of 49% with smooth pavement. If the pavement surface was smooth, and the radius of curvature is 180 ft. Assume the weight of the Truck is 8000 lb and while the weipht of GMC is 4500 Ib. Moreover, the cross-sectional area of the car is 45 r while Truck is 95 r. If the following information available: Density of air (p) 0.0766 Ib/t, Aerodynamic drag coefficient Ca 04 for cars and 0.5 for Trucks. C, and C-0.02445 and 0.00044 sec.ft for trucks,while Ce and Cre = 0.012 and 0.65 10
