It comes with practice. I hope at least that you feel you are getting better and better (even if slowly).J-dizzal said:i really need to work on recognizing what is the logical next step to take with what information i have. i spend way too much time on a single problem
I didn't use that method, but it would work. You had the dot product right [itex](62\hat i-mg\hat j)\cdot(0\hat i+\hat j)=-mg[/itex] but then you are supposed to divide by [itex]\sqrt{(mg)^2+62^2}*1[/itex] but for some reason you were dividing by mg. That's why in post #30 I said the magnitude of the net force is not mg.J-dizzal said:did you find the angle with the arccos method? what values did you use for a and b? i could only get 180degs
I think it was just a careless mistake, just got to take things slow.
