Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal stresses would be no greater than 16.0 ksi . the cylindrical pressure vessel has an inside diameter of dc = 27.0 in and a thickness of tc = 1.00 in . the spherical pressure vessel has an inside diameter of ds = 26.0 in and a thickness of ts = 0.250 in .

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.
