A rear-wheel-drive car is stuck in the snow between other parked cars as shown. To free the car, three students exert forces on the car at points A, B, and C while the driver’s actions result in a forward thrust of 40 lb acting parallel to the plane of rotation of each rear wheel. Treating the problem as two-dimensional, determine the equivalent force–couple system at the car center of mass G and locate the position x of the point on the car centerline through which
