Determine the magnitude P and direction θ of the force required to impart a rearward acceleration α = 5 ft/sec2 to the loaded wheelbarrow with no rotation from the position shown. The combined weight of the wheelbarrow and its load is 500 lb with center of gravity at G. Compare the normal force at B under acceleration with that for static equilibrium in the position shown. Neglect the friction and mass of the wheel.
