PROBLEM 31EA thin triangular plate of uniform density and thickness has vertices at v1 = (0, 1), v2 = (8, 1) and v3 = (2, 4), as in the figure below, and the mass of the plate is 3 g. a. Find the (x, y)-coordinates of the center of mass of the plate. This “balance point” of the plate coincides with the center of mass of a system consisting of three 1-gram point masses located at the vertices of the plate.b. Determine how to distribute an additional mass of 6 g at the three vertices of the plate to move the balance point of the plate to (2, 2). [Hint: Let w1, w2, and w3 denote the masses added at the three vertices, so that w1 + w2 + w3 = 6]

ANSWER:SolutionStep 1 of 5A thin triangular plate of uniform density and thickness has vertices at v1 = (0, 1), v2 = (8, 1) and v3 = (2, 4) and the mass of the plate is 3 g.So We have to find the (x, y)-coordinates of the center of mass of the plate. This “balance point” of the plate coincides with the center of mass of a system consisting of three 1-gram point masses located at the vertices of the plate.
