Speed of Hawk's shadow on the level ground = 3.29 m/s

Explanation:

When the sun is directly above the head of hawk shadow will be directly below hawk. So the speed of hawk's shadow will be equal to speed of hawk's in X - direction.

Velocity of hawk = 5.35 m/s

Angle from horizontal = 52.00⁰

Horizontal component = 5.35 cos 52.00⁰ = 3.29 m/s

So speed of hawk's shadow = 3.29 m/s
