Answer:
9.6 m
Explanation:
This is a case of motion under variable acceleration . So no law of motion formula will be applicable here. We shall have to integrate the given equation .
a = 3.6 t + 5.6
d²x / dt² = 3.6 t + 5.6
Integrating on both sides
dx /dt = 3.6 t² / 2 + 5.6 t + c
where c is a constant.
dx /dt = 1.8 t² + 5.6 t + c
when t = 0 , velocity dx /dt is zero
Putting these values in the equation above
0 = 0 +0 + c
c = 0
dx /dt = 1.8 t² + 5.6 t
Again integrating on both sides
x = 1.8 t³ / 3 + 5.6 x t² /2 + c₁
x = 0.6 t³ + 2.8 t² + c₁
when t =0, x = 0
c₁ = 0
x = 0.6 t³ + 2.8 t²
when t = 1.6
x = .6 x 1.6³ + 2.8 x 1.6²
= 2.4576 + 7.168
= 9.6256
9.6 m
Answer:
I don't know if it's fair for me to write an entire essay for you
but if you would like I can list some reasons you can incorporate into an essay.

-If you are joining a gang you are most likely going to have a greater chance of being targeted, even if it seems like you would be protected.
-Most of the time when someone joins a gang a child is being separated from a parent and will face most aggression.
-This can also cause academic failure in students, from lack of education and probably a pretty bad background.
-For teens when joining a gang they will do things that aren't suited for their age (I would list things but I'm not trying to get myself reported if you know what I mean)
-You will also have a great risk of being imprisoned and facing bad consequences, and these consequences can even be having the death penalty.

I hope this is good enough, sorry I didn't give you a full essay. I think this should help with that though.
this process is called parellelogram method of resolving vectors.
Using Kepler's third law which is defined as the square of the average distance is directly proportional to the cube of the period. It is expressed as P^2 = a^3, Given that the a = average distance is given, the period would be much easier to compute. P = sqrt(27^3) = 140
The answer is c. it requires no works
