Homework Help: Horizontal Distance For Guy Landing onto a running horse

  1. Aug 25, 2011 #1
    1. The problem statement, all variables and given/known data

    The man is 3m high from the saddle on a tree limb. The horse is running at 10m/s.

    A) What is the horizontal distance necessary for the men to land on the horse

    B) How long is he in the air



    2. Relevant equations

    I used y/accel to get the amount of time for him to hit the saddle
    Then multiplied by V of the horse to get the horizontal distance

    3. The attempt at a solution

    I divided 3m/9.8m/s to get the amount of time for him to hit the saddle which was .306

    and multiplied by 10m/s to get the distance needed for the horse to be away from the man. So 3.06 meters.

    The answer in the back of the book says 45. (a) 7.82 m (b) 0.782 s

    I'm not even close so can someone tell me what I'm missing?

    Well for a start the acceleration due to gravity is 9.8 m/s^2, not a velocity so your time to fall will be wrong

    OH my goodness... I knew it wasn't that simple. Thank you for pointing that out to me. Much appreciated.
