Question on tension in a vine

  1. Jul 26, 2011 #1
    1. The problem statement, all variables and given/known data
    Jill of the jungle swings on a vine 6.9 m long (assume no friction)

    what is the tension in the vine if jill, whose mass is 65 kg, is moving at 2.4m/s when the vine is vertical? Draw a free body diagram

    Assume Jill stops holding on at exactly the moment the vine is vertical and lands on the ground exactly 2.5 seconds later. What is her vertical speed when reaching the ground?

    How does the tension in the vine change if her mass is doubled? How does this effect her velocity when reaching the ground? explain

    2. Relevant equations



    3. The attempt at a solution

    was thinking you could use T=ma.. thus 65* 2.4 =154 N

    Hi MaggieNF! Welcome to PF! :wink:
    but 2.4 is v, not a :redface:

    you need to find the https://www.physicsforums.com/library.php?do=view_item&itemid=27" :smile:
