The path of a rolling marble rolling off of a desk can be modeled by the parametric equations: x(t)= 2.5t y(t)=-16t^2+3, In these equations the horizontal and vertical positions of the marble x(t) and y(t) are in the feet and t is measured in seconds. A) The marble will hit the ground after how many seconds? B) Using your answer to A, how far horizontally from the edge of the table will the marble first hit the ground? C) The parametric equations above can be expressed as the following single rectangular equation:
