Apitot-static tube is mounted on a 2.5 cm pipe where oil = 860 kg/m3, = 0.0103 kg/m·s) is flowing. the pitot tube is positioned such that the local velocity measured is similar to the mean velocity through the pipe cross section. the pressure difference is measured to be 95.8 pa. find the volumetric flow rate in m3/s.

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.
