###### When a vehicle is traveling at a constant velocity, the forceproduced by the engine must match the total resistive forcesof friction and drag to maintain a constant velocity. Ifa semi-truck engine produces energy at a rate of 463 hp to maintaina constant velocity of 73 mph, what is the magnitude of thecombined friction and drag forces in SI units on the truck? (Assumethat 1 m/s = 2.237 mph)
