Question

A pelican flying along a horizontal path drops
a fish from a height of 5.0 m. The fish travels
8.5 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?
Answer in units of m/s.

Answer 1

how long to fall?

5 = 4.9 t^2
solve for t

how far horizontal? (same horizontal speed as bird, not horizontal force, fish lands exactly under bird, turn to avoid splash.

8.5 = u t and we know t so get u
