Figure 2 shows a 2000 kg lorry with a center of mass at G. Starting from rest, the lorry achieves a speed of 15 m/s under a constant acceleration after it has traveled 100 m. The front wheels are free to roll. Q8. What is the normal force of the wheels at A and B? ( ↑ ) (A) NA = 10.7 kN (B) NẠ=8.89 kN (C) NẠ=8.89 kN (D) NA=10.7 kN Ng =8.89 kN Ng = 10.7 kN Ng = 8.89 kN Ng = 10.7 kN
