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: ->->->->->->->->->->->-> : 0, .35N
• What is the vector from the first point to the second?
answer/question/discussion: ->->->->->->->->->->->-> : .35N
• What is the magnitude of this vector?
answer/question/discussion: ->->->->->->->->->->->-> : .35N
• 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: ->->->->->->->->->->->-> : 0 / .35 = 0
• What vector do you get when you multiply this new vector by the tension?
answer/question/discussion: ->->->->->->->->->->->-> : 0 * .35 = 0
• What are the x and y coordinates of the new vector?
answer/question/discussion: ->->->->->->->->->->->-> : 0, 0
