    How to Calculate the Motion of a Dropped Fish in a Projectile Problem

    Oh! I get it now. It would be the same speed as the bird, correct? So, 7.39 m/s ?

    How to Calculate the Motion of a Dropped Fish in a Projectile Problem

    Okay well I tried it in a new foruma: v2 = v02 + 2ay(y - y0) v2 = v02 + 2ay(y - y0) v2 = 0 + 2(-9.8)(0 - 4.69) v2 = 91.924 v = 9.59 m/s I come up with the same answer?
