## Grazes Group Title Word Problem one year ago one year ago

1. Grazes Group Title

2. Peter14 Group Title

think about how this could happen. Two forces of 50 and 25 N, resultant force of 25 N...

3. Grazes Group Title

That's exactly what I need- a diagram. I have no idea.|dw:1367460386063:dw| This is my best guess

4. Peter14 Group Title

the resultant for the two vectors is 25 N. The resultant for any two vectors has to be somewhere between$\left[ V_1-V_2 \right] and [V_1+V_2]$

5. Peter14 Group Title

in this case, what is the maximum and minimum sum of these vectors?

6. Grazes Group Title

I'm doing trig. I haven't learned that yet, I don't think

7. Peter14 Group Title

for this problem you don't need any of that.

8. Grazes Group Title

Then what do you need? o-o

9. Peter14 Group Title

find the maximum and minimum length of the resultant.

10. Grazes Group Title

Is the dotted line I drew the resultant? And even if it is, I don't see how it can be more than one value if the shape I drew is a parallelogram.

11. Peter14 Group Title

you are adding two vectors and you don't know the angle between them because that's what you're trying to find.

12. Grazes Group Title

Could you draw a diagram for me, please?

14. Grazes Group Title

I'm lost. My teacher never used a circle to solve these types of problems.

15. Peter14 Group Title

I used a circle because you don't know which way the second vector is going relative to the first one.

16. Peter14 Group Title

I give up. What's 50-25?

17. Grazes Group Title

25.

18. Grazes Group Title

|dw:1367461942678:dw| Which angle do I need to find?

19. Peter14 Group Title

|dw:1367462096748:dw| resultant is 25

20. Peter14 Group Title

|dw:1367462207710:dw| you are supposed to find that angle

21. Grazes Group Title

What happened to 38 degrees and 10 minutes?

22. Peter14 Group Title

it doesn't matter. there is only one way to get a resultant force of 25 newtons from forces of 50 N and 25 N.

23. Grazes Group Title

I will take your word for it.
