Re: vectorsI'll write the directions and magnitudes again....... #4 20060115 08:51:00
Re: vectorsFirst, we need to make these vectors. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #5 20060115 09:02:57
Re: vectorsRicky's method is perfectly correct. A quicker, but harder, alternative is to make the two known forces into two sides of a triangle and then use trigonometric formulae to find the length and angle of the third side. Why did the vector cross the road? It wanted to be normal. #6 20060115 09:58:30
Re: vectorsYou can break up as many vectors as you want to add or subtract and use the Pythagorean theorem. #7 20060115 10:13:05
Re: vectorsI'm sorry, I forgot about the F1  F2 equation, but it really is no different than what I stated above. My last post was F1 + F2. The only difference in that calculation and the subtraction one is that you must use the negative components of F2. All of the summation and equation still hold true.
