Using the following formula for linear-motion, the missing variable can be solved:
s = Vi * t + 1/2 (a * t^2)
Where: s = displacement = 29.7 m
Vi = initial velocity = 8.5 m/s
a = acceleration = 9.8
t = time = ?
Substituting:
29.7 = 8.5t + 1/2 (9.8*t^2)
29.7 = 8.5t + 4.9t^2
Dividing both sides by 4.9:
6.06 = 1.73t + t^2
t^2 + 1.73t - 6.06 = 0
(t - 1.74)(t + 3.48) = 0
t = 1.74s
From the above values, the correct answer is 1.74 seconds.

Answer:
C sedimentary rocks is the answer.
Explanation:
The US shouldn't cut the space exploration budget because rare-earth materials are used to make shuttles and satellites.
Advantages of exploring space are:
We can learn a lot about star systems, black holes, and gravity.
We can see earth's surface and know what rival countries are doing.
We can find earth-like planets.
There are more, but these were the quickest to come to mind for me~!
