These two images show pairs of oppositely charged plates that create uniform electric fields. The strength of
the field on the right is twice as strong as that of the
field on the left. In the field on the left, a positive charge
changes position as shown. In the field on the right, a
negative charge that has twice the magnitude of the
positive charge is placed midway between the plates.

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.
