![]() ![]() The graph is going at a angle upwards showing that it is increasing at a constant speed. The yt graph also starts with a velocity of zero. The graph is curved showing the velocity increasing as it goes back to zero moving downward. The vx velocity graph is not changing or moving which is showing us constant velocity. The vy horizontal graph is going at a constant velocity downwards. The equation delta y=1/2 at^2+voyt is used because the motion of the ball is free mall motion, and free fall motion is shown best with this equation because -9.8m/s^2 is used for the gravitational fall.The balls velocity starts at the axis with a velocity of om/s.
