Homework Help: Conservation of mechanical energy problem

  1. Oct 15, 2008 #1
    1. The problem statement, all variables and given/known data
    A bird is flying with a speed of 18.0 m/s over water when it accidentally drops a 2.00 kg fish. If the altitude of the bird is 5.40 m and friction is disregarded, what is the speed of the fish when it hits the water?


    2. The attempt at a solution

    I tried v^2= 2(9.8)(5.4) but didn't get the correct answer.

    use delta KE initial = delta KE final

    and solve for V
