- A person is pushing a fully loaded 24.55 kg wheelbarrow at constant velocity along a plank that makes an angle a = 43.0° with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its 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. F = NThe thin ring can be adjusted vertically between three equally long cables from which the 300 kg chandelier is suspended.
