The answer would be A. There is a phase shift to the left. Because you are adding pi/6.
You may find it easiest if you convert all the fractions to decimal form:
5.433...
5.166...
5.756
Now reorder these from smallest to largest.

9,846,000,000,000 = <span>9.846 x 10^12
answer
</span>9.846 x 10^12
S = ut + (1/2)a(t²) Subtract ut from both sides
(1/2)a(t²) = S - ut Multiply both sides by 2
a(t²) = 2s - 2ut Divide both sides by t²
a= 2s/t² - 2u/t
a= (2S - 2ut)/t²
Answer is C) but there should be parentheses around the term (2S-2ut)
3/8 meters squared because 3/4x1/2 = 3/8m
