A person is pushing a fully loaded 25.40 kg wheelbarrow at constant velocity along a plank that makes an angle a = 32.0° with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length L. What is the magnitude of the total force F, the person must apply so that the wheelbarrow is parallel to that plank? You may neglect the radius of the wheel in your analysis. The gravitational acceleration is g = 9.81 m/s².
