Apelican 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 water below. the acceleration of gravity is 9.81 m/s2 .
a) what was the pelican’s initial speed?
b) if the pelican was traveling at the same speed but was only 2.7 m above the water, how far would the fish travel horizontally before hitting the water below?
