2.Two boys are playing with slingshots on the side of a bridge. One boy pulls his slingshot back very far before launching his rock, while the other boy barely stretches his at all. If they each launch their rocks horizontally from the same place, which rock goes further? Why?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
