8. Figure 7 shows a four-wheel drive car of mass m= 970 kg. The coefficients of friction is u-0.6. Neglect the mass of the tyres. (a) Determine the greatest possible acceleration of the race car so that its front tyres do not lkave the ground nor the tyres slip on the track. (b) Determine the corresponding reactions on tyres A and B.
