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.

Why is 236.9 N wrong?
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

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.
