A person pushing a uniformly‑loaded 34.7kg wheelbarrow of length L with pushing force P is attempting to get it over a step. The maximum horizontal force that the person can apply is P=617N. What is the maximum height h of the step, as a fraction n of the wheel's radius R , that the person can get the wheelbarrow over?

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...

Sam is trying to move a dresser of mass m and dimensions of length L and height H by pushing it with a horizontal force F⃗ applied at a height h above the floor. (Figure 1) The coefficient of kinetic friction between the dresser and the floor is μk and g is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes NP and NQ at the two ends of the dresser. Note that...
