The car in Figure 2 (mass 1500 kg) is braked on all four wheels to the limit of adhesion (μ = 0.60) from 72 km/h on a level road. The positions of the centre of gravity G and the wheelbase are shown. Determine (a) the load on the front axle during braking (answer in kN) and (b) the stopping distance, neglecting the driver's reaction time (answer in m).
