SEED 16.1
A rubber band has no tension until it reaches a length of 7.5 cm. Beyond that length its tension increases by .7 Newtons for every additional centimeter of
length.
What will be its tension if its endpoints are at the points (5 cm, 9 cm) and (10 cm, 17 cm) as measured on an x-y coordinate system?
answer/question/discussion: d^2 = 25 + 64
d = 9.4
Addtl length over 7.5 = 1.9 cm
.7(1.9) = 1.33 N
What is the vector from the first point to the second?
answer/question/discussion:
The vector is 9.4 cm long...
It's slope is 5/8
What is the magnitude of this vector?
answer/question/discussion:
Its magnitude is its length correct?
So the magnitude would be 9.4
What vector do you get when you divide this vector by its magnitude? (Specify the x and y components of the resulting vector).
answer/question/discussion:
I am not sure what you mean by this vector
What vector do you get when you multiply this new vector by the tension?
answer/question/discussion:
9.4/1.33 = 7.1 cm vector
What are the x and y coordinates of the new vector?
answer/question/discussion:
I do not know how to do this, I am confused as to how this works

Theoretically you should be able to answer these questions based on Intro Problem Set 5. In practice, these operations aren't completely familiar to most students and the instructions therefore do give most students trouble, in which case this problem serves as an introduction to certain concepts. See the link below for a detailed explanation, and do submit the requested revision so we can be sure you have all the explanation you need.
