Jumping into a pool from a balcony

  1. Oct 27, 2008 #1
    1. The problem statement, all variables and given/known data

    Harry and Hermione look from their balcony to a swimming pool below that is 14.0 m from the bottom of their building. They estimate the balcony is 32.0 m high and wonder how fast they would have to jump horizontally to succeed in reaching the pool. What is your answer? Enter m/s as unit and round g = 10 m/s^2.

    3. The attempt at a solution

    im sorry, i just cant think right now... its so late and all of this is due tomorrow... help?

    y=32
    x=14

    y=-.5at^2
    2y/a=t^2.... square root that

    (2y/a)1/2=t

    X=Vot
    X/t=Vo

    X/(2y/a)1/2=initial velocity
