A 2.00-m by 4.00-m uniform sheet of plywood is in a coordinate system with the origin at its center, the x-axis along the longer dimension of the sheet is positive to the right and the y-axis along the shorter dimension is positive upwards. The section of the plywood in the 3rd quadrant is sawed off and the resulting piece is then glued squarely over the 4th quadrant portion of the plywood with glue of negligible weight.What are the x- and y-coordinates of the resulting center of gravity for this arrangement?
Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
