Emmy kicks a soccer ball up at an angle of 45Β° 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 β and βdirections, respectively, and use β10 m/s2 for the downward acceleration due to gravity.
