A 7000-lb truck (weight of the truck =7000 lb) is being used to lift a 1500-lb boulder B (weight of boulder B = 1500 lb) that is on a 200-lb pallet A (weight of pallet A = 200lb). Knowing the acceleration of the rear-wheel drive truck is 2 ft/s2, determine (a) the reaction at each wheel (front and rear), (b) the force between the boulder and the pallet. 3 ft < <5 ft 4 ft 3 ft 1 ft A
