Answer:

2.71 m/s

Step-by-step explanation:

Apply the formula for cosine of an angle where;

The hypotenuse is the speed the hawk dives towards the ground : 3.31 m/s

The angle of direction of motion from the horizontal is : 35°

Speed of the shadow along the ground will be, A ;

Cosine 35° = A / 3.31

A= 3.31 cosine 35°

A= 2.71 m/s
