A cannon fires a .79 kg shell with an initial velocity Vi=12 m/s in the direction 59 degrees?
A cannon fires a .79 kg shell with an initial velocity Vi=12 m/s in the direction 59 degrees above the horizontal.The shells trajectory curves downward because of gravity, so at the time t=0.237 s the shell is below the straight line by some vertical distance h. On what does delta h depend besides g?
1. It depends only on the initial angle θ, and does not depend on the flight time t nor on the initial velocity vi.
2. It depends on the initial angle θ and the initial velocity vi, but does not depend on the flight time t.
3. It depends on the flight time t and the initial velocity vi, but does not depend on the initial angle θ.
4. It depends only on the initial velocity vi, and does not depend on the flight time t nor on the initial angle θ.
5. It depends on some data not given in the problem.
6. It depends on everything: the flight time t, the initial angle θ, and the initial velocity vi.
7. It is a constant and does not depend on the flight time t nor on the initial velocity vi nor the initial angle θ.
8. It depends on the flight time t and the initial angle θ, but does not depend on the initial velocity vi.
9. It depends only on the flight time t, and does not depend on the initial velocity vi nor on the initial angle θ.
It's not 6 :/

The projectile will be 0.056169 meters below its initial straight-line trajectory.
h = 9.2 / 2 * 0.237^2 = 0.056169
This is true regardless of changes to any other parameters (as no other parameters are included in the above equation.
(Unless, of course, the ground gets in the way.)
