    Finding acceleration and velocity
    Anna walks off the end of a 10.0 m diving platform
    a) What is her acceleration in m/s2 toward the pool?
    b) how long does it take her to reach the water?
    c) What is her velocity when she reaches the water?

    Hints:

    any thing falling freely has acceleration (due to gravity) = g

    If u is initial velocity, a is acceleration, and s is distance travelled, the following quadratic
    will you give you the time taken t, which must be a positve number!

    s = ut + 1/2 at^2

    If you know time t, initial velocity u, acceleration a, the following gives you final velocity v:

    v = u + at


    I hope the above helps.
