Solve Basic Vector Problem: Hawk Speed & Shadow Speed in m/s

[olliepower]

Homework Statement

When the Sun is directly overhead, a hawk dives toward the ground at a speed of 4.24 m/s

If the direction of his motion is at an angle of 61.7 below the horizontal, calculate the speed of his shadow along the ground

Answer in units of m/s

Homework Equations

A_x = A cos$\theta$

The Attempt at a Solution

I will want to find the x component of the velocity vector.

4.24 Cos (-61.7) = 2.01013

I put this answer into my homework program (Quest) and it was wrong. What am I missing here?

Welcome to PF, Ollie. Your calc seems correct to me.
Sounds like a good opportunity to visit your prof.
