a. Determine the maximum resistive force experienced by the vehicle when it travels at a speed of 100 km/h with a tailwind of 3 m/s
b. Determine the required tractive force for it to travel with a constant acceleration of 3.8 m/s2 from 0 to its top speed of 160 km/h on a flat ground without any headwind or tailwind.
