Answer:
<em>(a) t = 4.52 sec</em>
<em>(b) X = 1,156.49 m</em>
Explanation:
<u>Horizontal Launching
</u>
If an object is launched horizontally, its initial speed is zero in the y-coordinate and the horizontal component of the velocity 
remains the same in time. The distance x is computed as
.
(a)
The vertical component of the velocity 
starts from zero and gradually starts to increase due to the acceleration of gravity as follows
This means the vertical height is computed by
Where 
is the initial height. Our fighter bomber is 100 m high, so we can compute the time the bomb needs to reach the ground by solving the above equation for t knowing h=0
(b)
We now compute the horizontal distance knowing 
A robin is a small carnivore bird which feed on insects, earthworms, spiders and bees. It needs about 60 calories per day from these organisms. This bird has a short lifespan of only 7 years. Hope this answers the question. Have a nice day.
