A person pushes a fully loaded $25\mathrm{.}25$ kg wheelbarrow at constant velocity along a ramp that makes an angle $=21\mathrm{.}0$ with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length $L.$

Assume that the radius of the wheel is negligible and that the wheel rolls without slipping. The gravitational acceleration is $g=9\mathrm{.}81\frac{m}{s^2}.$

What is the magnitude $F_{\text{n}\text{e}\text{t}}$ of the net force that the person must apply to keep the wheelbarrow parallel to the ramp?
