Homework Help: Fish and Pelican Problem

  1. Sep 12, 2006 #1

    54) A small fish is dropped by a pelican that is rising steadily at 0.50 m/s.

    a) After 2.5 s, what is the velocity of the fish? Ans: -24 m/s

    b) How far below the pelican is the fish after 2.5 s? Ans: 31m

    My Work/Question:

    The fish would be moving at the same velocity as the pelican, which equals the (Vi). The Accel would equal -9.81 m/s^2 due to gravity.

    I used Vf = (Vi) + (A)(T) to find the velocity of the fish.

    My question on B: Would I use the.... delt X = (Vi)(t) + (1/2)(A)(T)^2....formula for B?

    DO NOT REPLY....I've already figured it out
