Homework Help: Free fall question

  1. Mar 9, 2009 #1
    1. The problem statement, all variables and given/known data
    A small first-aid kit is dropped by a rock
    climber who is descending steadily at 1.2 m/s.
    a) After 4.2 s, what is the velocity of the
    first-aid kit? Answer in units of m/s.

    Ok i know that the velocity after the 4.2 sec is -42.36 however the question asks how far is the kit below the climber after the 4.2 sec.
    I tried using deltay=vit+1/2at^2 but it is wrong
    can someone help me or tell me what is it iam doing wrong?

    Did you also account for the distance the climber descended while the kit was dropping?
