A pelican ﬂying along a horizontal path drops
a ﬁsh from a height of 3.1 m. The ﬁsh travels
6.4 m horizontally before it hits the water
What was the pelican’s initial speed? The
acceleration of gravity is 9.81 m/s
Answer in units of m/s
how long does it take to fall 3.1meters?
then, use that time to calculate horizontal velocity distance/time
