A pelican flying along a horizontal path drops a fish from a height of 5.5 m. The fish travels 7.0 m horizontally before it hits the water below.

Question

What was the pelican’s initial speed? The
acceleration of gravity is 9.81 m/s^2.

Answer 1

7.0 m/(time to fall 5.5 m)

Time to fall Y = = sqrt (2Y/g)
= 1.059 s for Y = 5.5 m

Now use the first equation
