A small cart is rolling at constant velocity vo on a flat track. As it continues to move, a launcher, fixed
onto the cart, fires a marble straight up into the air when the end of the launching barrel is passing point
i, as shown in the figure. If the launching barrel reaches the position of point ii when the marble returns
to the same vertical position that it was launched from, what will be its horizontal position? (Assume air
resistance is neglible)
