A person is pushing a wheelbarrow along a ramp that makes an angle a = 39.0° with the horizontal. The wheelbarrow and load have a combined mass of m = 29.85 kg with the center of mass at the midpoint of the F length L. What is the magnitude of the net force Fnet that the person must apply in order to push the wheelbarrow up the ramp at a constant velocity, while keeping the wheelbarrow in a level, horizontal orientation? Assume that the radius of the wheel is small enough to ignore. Use g = 9.81 m/s².
