5. Two rocks are thrown at the same time from the top of the same cliff. Graphs of the horizontal and vertical velocity as a function of time are shown for each rock. The coordinate system is defined with up the positive vertical direction, and the away from the base of the cliff the positive horizontal direction. You may ignore air resistance. For all parts to this question you must explain your answer clearly and concisely Rock A Rock B V (horizontal) V (horizontal) time time V (vertical) V (vertical) time time A) Which rock was thrown with the greatest initial speed, or were they thrown with the same speed? B) Which rock was thrown at the greatest initial angle measured relative to the positive horizontal direction, or were they thrown at the same angle? C) Which rock hits farthest from the base of the cliff, or do they hit at the same distance? D) Which rock hits the ground first, or do they hit at the same time
