Question

A pelican flying drops a fish from a height of 8.1 m. The fish travels 9.3 m horizontally before it hits the ground. The pelican’s speed was

Answer 1

Using kinematics: 8.1 = 1/2(9.8)(t^2),
t = 1.2857 s.
Horizontal distance x travelled is x = vhorizontal * t, so 9.3 = v*1.2857, or v= 7.233 m/s horizontally.
