13) There are several types of drag on a car other than airresistance. Effects having to do with the squeezing of the tires(rolling resistance) and frictional forces in the drivetrain (thesystem that transfers energy from the engine to the rotation of thewheels) also must be taken into account. Engineers use thefollowing equation to model the total force due to these differenteffects Fdrag=A+Bv+Cv2Fdrag=A+Bv+Cv2 For a Camry, thesecoefficients are estimated to be A=117.130A=117.130 N, B=1.800 Ns/mB=1.800 N s/m, and C=0.368 N s2/m2C=0.368 N s2/m2. Suppose thatthe driver steadily accelerates the car from 0 km/hr to 100 km/hrover a 3.4 s. What is the magnitude of the work done by the dragforces? Hint: What is the instantaneous power of the drag? What isthe relationship between that and the total work done by dragforces? Which kinematic model can you use to relate velocity, time,and acceleration? a) How much energy is lost to drag when the cartravels 35 km at 31 m/s? Answer: b) The car drives a distance 110 mup a section of road whose grade is 20% (the grade is the verticalrise of the road as a percent of the horizontal run of the road).The car's speed is 31 m/s. The car has a mass of 1543.60 kg. Whatis the minimum amount of power needed for the car to drive up thissection of road, assuming perfect efficiency? I already have thefirst part don I just dont know how to do the last two parts ofthis one question
