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?

Re: a pelican flying along a horizontal path....

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
