Will there be an instance in which the wave interference is at the same level as point X?
O No, the interfering waves will always be above X.
No, the interfering waves will always fall below X.
O Yes, the overlap will occur during the slope of the
waves.
Yes, the overlap will occur when the first wave hits
point X

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.
