Center of mass about an axis is given by:
The two 100 g masses are located at y = 0 cm. The 200 g mass is located at the height of the triangle. Using Pythagoras theorem, the height of the triangle is:
h = [hyp2 - (base/2)2](1/2) = (102 - 62)(1/2) = 8 cm
Find the y-coordinate.
Express your answer to two significant figures and include the appropriate units.
