1.

The masses m, are located at the points Pi. Find the center of mass of the system. m1 = 4, m2 = 8, m3 = 9. P1 = (9, 2), P2 = (3, 4), P3 = (- 6, 8). T= U =Find the centroid of the region bounded by the graphs of the functions y = 416, y = x- + 3 The centroid is at (@, y ) where T= =\fCompute the center of mass I on a rod of density p(@) = 3x* + re with r E (0, 4). T Round to 4 decimal places. Use technology as needed.
