    1. The problem statement, all variables and given/known data


    "A cat is climbing a vertical ladder from h=3m with the constant speed of v=4m/s. At the same time from the ground it's thrown in the air an object (small dimension) g=10m/s2. Find out the initial speed of the object knowing that it will meet with the cat a single time. (vo=?)

    2. Relevant equations

    y1=y2
    va + a(t-to)-va root 2+2a(x-xo)

    3. The attempt at a solution



    First attempt: http://imgur.com/h84NXzO,B73etyF + drawing second image

    I need to find out 2 with the Galilei equation and the speed one

    Looks correct, but I think you should add a numerical answer as you got values for v and h.
