Projectile Motion on Planet X


The above graph shows the trajectory of a projectile launched on a planet X (where the acceleration due to gravity is unknown).  Using the data available on the display determine the components of the initial position vector, the initial velocity vector, and the acceleration vector.  Combine this information to write a vector equation for the position of the object as a function of time in the boxes below.  When done correctly, the target sight (black circle with cross hairs) will follow the ball so that the ball is always in the target.

x(t) =
y(t) =
