1. Conceptual Question! A 15kg rock is thrown horizontally at the same time that a 5g ball is dropped from rest, from the same height as the ball. Their trajectories are shown in figure 1: Point A is the release point for both objects; at point B, both objects have been traveling the same amount of time from the time of release; at point C, both objects are just about to hit the ground. Ignore air resistance in this problem. a. For both objects, go to figure 1 and draw the vectors , x, y, and a for points A, B, and C, where applicable. Indicate on the figure which vectors have the same magnitude. (10pts.) maga have came BW E b. Which will have the greater speed when it reaches the ground (point C), the rock or the ball?
