The resistance to motion is given by R, = (0.011 · 0.000 06 5 Mg + 0.028 AV² where M is the mass in kg, V is velocity in km/h and A is the frontal area in i:?. A jeep of 1400 kg mass and 2.4-m² frontal area is used to pull a trailor with a gross mass of 800 kg at 50 km/h in top gear on level road. If the jeep is capable of developing 40 kW of power for propulsioro ofd whether it is adequate for the job. The trałvsmission efficiency may be taken as 92%. Also, find tkr vll on the coupling at this speed. If all the power is used by the loading trailor, determine the pull in the coupling at 50 km/h and the load put on the trailor.
