Find velocity of a moment before terminal velocity is reached?

  1. Oct 9, 2012 #1
    1. The problem statement, all variables and given/known data
    Given g = 9.8 m/s
    2
    .
    A sky diver of mass 69 kg jumps from a
    slowly moving aircraft and eventually reachesher terminal velocity 56 m/s.
    What was (the magnitude of) her acceleration at the moment her velocity was only
    v1 = 39 m/s (directed vertically down)?
    Answer in units of m/s2
    I got the answer to this as 5.0468


    Now consider the same sky diver jumping out
    of a faster airplane. At some point before she
    reaches her terminal velocity, she has velocity
    ~v2 of magnitude 34.2 m/s in the direction 56◦
    below hirizontal.
    What is the magnitude of the sky diver’s
    acceleration at that point in time?
    Answer in units of m/s2

    i have no idea how to do this one. Can someone show me how or point me in the right direction
    2. Relevant equations



    3. The attempt at a solution

    Is there something missing here ↑↑↑ perhaps due to mis-editing?
    Can you show your working so we can see how you did it? I don't get that answer.
