Question

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.

Answer 1

Well, how long does it take to fall 53 meters?

53 = (1/2)(9.81) t^2
t = 3.3 seconds
