Answer: This is the graph for -x -2y=4
Y = yo + Vot - (gt^2)/2
y = 10 + 27t - 16.087t^2 [I used g = 32.174 ft/s^2]
You can find y with the quadratic formula or probe with the different times given.
I tried with t = 2 s and found
y = 10 + 27(2) - 16.087 (4) = 10 + 54 - 64.348 = -0.348
Then that is the answer, t = 2s.
10/40 or 1/4 is the rest of the amount needed to fill the tank up hope I helped.
