A pelican flying along a horizontal path

  1. Oct 20, 2012 #1
    a pelican flying along a horizontal path....

    A pelican flying along a horizontal path drops a fish from a height of 5.4 m. The fish travels 8.0 m horizontally before it hits the watwe below. What was the pelican's initial speed?


    Well I'm guessing that y =-5.4m and x= 8.0 m...what do I exactly do after....meaning how do I solve this?

    How long does it take to fall 5.4 m? What kinematic equations describe the vertical motion?

    Y=viy+at?

    No. Where did you get that equation? (Note that each term in that equation has different units, so it cannot possibly represent something real.)

    Look here for a list of kinematic equations: Basic Equations of 1-D Kinematics
