A hawk flying at a height of 60 feet spots a rabbit on the ground If the hawk dives at a speed of 55 feet per second how long will it take the hawk to reach the rabbit?

The time would depend on some variables. Unless the hawk is flying directly over the rabbit there would more than 60 ft between it and the rabbit. Hawks do not normally dive straight down, they dive more at an angle in order to catch their prey in their claws and continue to fly off with it. Another vairable would be if the rabbit would run after spotting the hawk coming toward it.
However, if this is just a distance versus time mathematical question, divide the distance by the time in order to find how quickly the hawk would get to the rabbit. 60 ÷ 55 = 1.09 seconds.
I did not ask that I asked what does a nighthawk eat and you are telling me how many seconds it will take to eat their prey so answer that question correctly not trying to be mean

The hawk reaches the rabbit at t=4.3 sec
Step-by-step :
Let
h ----> is the height in feet
t ----> is the time in seconds
v ---> the initial velocity in feet pr second
s ----- is the starting height
we have
H=-16t^2+vt+s
when the hawk reaches the rabbit the value of h is equal to zero
we have
V=55ft/sec
S=60ft
substitute
0=-16t^2+55t+60
Solve the quadratic equation by graphing
The solution is t=4.3 sec

An angry construction worker throws his wrench downward from a height of 128 feet with an initial velocity of 32 feet per second. The height of the wrench above the ground after 1 second is what?
s=u*t +1/2*a*t*t u=32 t=1 a=33 s=48.5 hence height above ground=128-48.5 =79.5 feet
A stone was dropped off a cliff and hit the ground with a speed of 96 ft per second what is the height of the cliff?
240 ft
If an object is thrown upward with an initial velocity of 32 feet per second from 40 feet above the ground write the height equation?
The height, in feet, above the ground at time t, H(t) = 40 + 32*t - 16*t2
You drop a penny from a height of 16 feet After how many seconds does the penny land on the ground?
1 second, since all objects fall at 16 feet per second.

You drop a 5 kilo ball from rest from a height of 20 meters how fast is it moving when it strikes the ground?
20 meters per second
Why dropped objects hit the ground at the same time?
Dropped objects hit the ground at the same time (as long as they're dropped from the same height) because the acceleration of gravity is constant. On earth, it's 9.8 meters per second (32.2 feet per second) every second.
