Step-by-step explanation:
Let the centerline of the canal be the x-axis. Because the forces exerted by the horses are symmetric to the centerline, only the x-components of these forces contribute to the resultant force on the barge, i.e., the y-components cancel out. Each x-component is equal to = 810.4 N. Therefore, the resultant force on the barge is twice this:
The slope of a line often referred to as the () is the rate of change in a line. It can be found using the following formula.
Where () and (
) are points on the line. For each problem, substitute the points on the line into the formula and solve for the slope.
