When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 4.15 m/s at 54.5° below the horizontal. Calculate the speed of her shadow on the level ground.
vxi=vicosθ vyi=visinθ (i think)
360-54.5=305.5
4.15cos305.5=-2.99i
4.15sin305.5=-2.88j
then get the modulus of the vector for the speed. Gave me 4.155
Its wrong though?
Help?
Tell me where I went wrong and where to begin
Thanks
