Answer 1

The correct answer is definitely C.  Note how the highest off the ground that the object will ever be is 120 ft, and that the -16*t^2 term clearly demonstrates that the object is falling from height 120 ft.  That -16 comes from g, the acceleration due to gravity, which is -32 ft per (second squared).

Answer 2

I believe the answer is C. It doesn't make sense to drop an object from -16 feet, and it doesn't make sense to have a -120 in the equation. It should be positive for it to come out right.
