The peregrine falcon is the fastest bird, flying at a speed of 200 mi/h. Nature has adapted it to reach such speed by placing baffles in its nostrils to prevent air from rushing in and slowing it. Also, its eyes adjust focus faster than any other creature so it can focus quickly on its prey. Assume it is moving horizontally at this speed at a height of 100 m above the ground when it brings its wings into its sides and begins to drop in free fall. How far will the bird fall vertically while traveling horizontally a distance of 120 m?
The answer is in m

assuming no air friction, it will retain this horizontal speed; converting 200 mi/hr to m/s gives us
89.6m/s
thus it takes a time of t = 120m/89.6m/s = 1.34s to travel this distance
in this time, it will fall a distance of:
dist = 1/2 gt^2 = 1/2*9.8m/s/s*(1.34s)^2 = 8.8m
89.6m/s
thus it takes a time of t = 120m/89.6m/s = 1.34s to travel this distance
in this time, it will fall a distance of:
dist = 1/2 gt^2 = 1/2*9.8m/s/s*(1.34s)^2 = 8.8m

I would love to answer but I am a Criminal Justice major, not a rocket scientist.
