Aseries r-l-c circuit is connected to a 110 hz ac source that has vrms = 80.0 v . the circuit has a resistance of 65.0 ω and an impedance of 104 ω at this frequency. what average power is delivered to the circuit by the source?

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.
