A person is pushing a fully loaded 24.50 kg wheelbarrow at constant velocity along a plank that makes an angle =42.0∘ with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length . What is the magnitude of the total force the person must apply so that the wheelbarrow is parallel to that plank? You may neglect the radius of the wheel in your analysis. The gravitational acceleration is =9.81 m/s2.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
