A non-conducting pipe has a uniform charge density of 71 mu or micro CC/m3. The inner radius of the pipe is 25 cm, while the outer radius is 30 cm. Calculate the magnitude of the electric field at r = 38 cm.

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.
