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 negligable, 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 x and y directions, respectively, and use g ≈10 m/s2 for the downward acceleration due to gravity.
the answer is suppose to be in two graphs, one for horizontal velocity and the other for vertical velocity. time along x-axis in .5sec increments.

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
