A peregrine falcon dives at a pigeon. The falcon starts downward from rest with free-fall acceleration. If the pigeon is 53.0 m below the initial position of the falcon, how long does the falcon take to reach the pigeon? Assume that the pigeon remains at rest.
Well, how long does it take to fall 53 meters?
53 = (1/2)(9.81) t^2
t = 3.3 seconds
