Center of Mass

 A hammer can be modeled as a <math display="inline"><mrow><mn>750</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> point mass on the end of a <math display="inline"><mrow><mn>42</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math> long, <math display="inline"><mrow><mn>200</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> uniform rod. How far from the head of the hammer is the center of mass? 

Intro to Center of Mass

 A <math display="inline"><mrow><mn>200</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> mass is at (0, 0), a <math display="inline"><mrow><mn>300</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> mass is at (<math display="inline"><mrow><mn>10</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math>, 0), and a <math display="inline"><mrow><mn>400</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> mass is at (<math display="inline"><mrow><mn>13</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math>, <math display="inline"><mrow><mn>15</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math>). What are the coordinates of the center of mass?
