Question

If a-b=6.0C and a+b=5.7C and C=5.3i+4.7j what are the x and y components of a &b for each equation?

Answer 1

I figured out the values of 6.0C and 5.7C, but I'm not sure what to do next.

Answer 2

If I'm understanding the problem correctly, what you'll want to do is add the first two equations together. Then b cancels out, and you're left with 2a=11c, c=2a/11, 2a/11=5.3î+4.7j. You can get the value of C by the Pythagorean Theorem. Namely:\[C=\sqrt{5.7^2+6.0^2}\]
