Which of the following explains why the Earth orbits the sun rather than the sun orbiting the Earth?
A. The force of Earth's gravity pulling on the sun has a smaller
magnitude than the force of the sun pulling on the Earth.
B. Even though the sun is pulled toward the Earth, the force is
opposed by forces from the gravity of the other planets.
C. While the Earth is pulled toward the sun with a gravitational force,
the sun is not pulled toward the Earth by a gravitational force.
D. Earth has a much smaller mass, so the gravitational force
accelerates the Earth much more than it accelerates the sun.

Gotta have a picture ^^

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
