Basic Vector problem

  1. Sep 7, 2011 #1
    1. The problem statement, all variables and given/known data

    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

    2. Relevant equations

    A_x = A cos[itex]\theta[/itex]


    3. 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.
