A 2000 kg truck is being used to lift a 400 kg boulder B that is on a 50 6 pallet A. Knowing the acceleration of the rear-wheel-drive truck is 1/m/s^2, determine (a) the reaction at each of the front wheels, (b) the force between the boulder and the pallet. Center of grav of truck, G, is 1 m off ground Front wheels to G is 1.4 m, g to rear wheels is 2 m, rear wheels to hitch point is 1.2m, hitch point is .6m off the ground.
