A person is pushing a wheelbarrow along a ramp that makes an angle 38 degrees with the horizontal. The wheelbarrow and load have a combined mass of 28.4kg with the center of mass at the midpoint of the length L. What is the magnitude of the net force 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^2/s^2. Please show free body diagram and torques.

A person is pushing a fully loaded 25.15 kg25.15 kg wheelbarrow at constant velocity along a plank that makes an angle α=28.0∘α=28.0∘ with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length LL . What is the magnitude of the total force FxFx the person must apply so that the wheelbarrow is parallel to that plank? You may negelct the radius of the wheel in your analysis.

John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of 0 = 18.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 379 N is exerted at the center of the wheel, which has a radius of 19.0 cm. Assume the brick remains fixed and does not slide along the ground. Also assume the...
