Question
Learning Goal:
The car shown has a mass of m= 950 kg and a center of mass
located at G. The coefficient of static friction between the wheels and
the road is s 0.220 The dimensions are a = 1.25 m,
b= 1.55 m, and c= 0.250 m Assume the car starts from rest, the
wheels do not slip on the road, and that the car experiences constant
acceleration Neglect the mass of the wheels (Figure 1)

Learning Goal:
The car shown has a mass of m= 950 kg and a center of mass
tocated at G. The coefficient of static friction between the wheels and
the road is 4,-0.220. The dimensions are a = 1.25 m,
b= 1.55 m, and c = 0.250 m. Assume the car starts from rest, the
wheels do not slip on the road, and that the car experiences constant
acceleration. Neglect the mass of the wheels. (Figure 1)
