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

    I can only attach one file So I will put a link to flickr.

    2. Relevant equations
    A avg.= delta v / delta t

    3. The attempt at a solution

    I have to do these problems for homework and usually when I have an issue with it I ask my teacher, thing is he has been out for the past two days and this is due tomorrow. All of them have work and equations on them but I do not know if they are correct. On numbers 22, 49, and 50 I could not find a logical answer. I think I may have the wrong equation for those.

    At your first problem, I don't think you used the correct height. Your total height equals 75 m plus the height that stone achieves after being thrown from the edge of the cliff with initial velocity of 12 m/s.
