A person is pushing a wheelbarrow along a ramp that makes an angle α = 41.0° with the horizontal. The wheelbarrow and load have a combined mass of 21.35 kg with the center of mass at the midpoint of the length L. What is the total force the person must apply so that the wheelbarrow remains horizontal on that ramp?
Homework Answers
net force needed to make the wheel barrow horizontal, wben the center of gravity ar mid point of the system
considering moment about wheel
F cos x* L = mg * ( L/2)
F cos 41 = 21.35* 9.8 / 2
F = 138.616 N

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.

A person pushing a horizontal, uniformly loaded, 26.40 kg wheelbarrow of length L is attempting to get it over a step of height h = 0.470R, where R is the wheel's radius. The center of gravity of the wheelbarrow is in the center of the wheelbarrow. What is the horizontal component Px of the minimum force P necessary to push the wheelbarrow over the step? The gravitational acceleration is g = 9.81 m/s2. PE

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...

A 24.1 kg box of textbooks rests on a loading ramp that makes an angle α with the horizontal. The coefficient of kinetic friction is 0.25 and the coefficient of static friction is 0.35. A) As the angle αα is increased, find the minimum angle at which the box starts to slip. B) At this angle, find the acceleration once the box has begun to move C) At this angle, how fast will the box be moving after it has...
