There are 5 light bulbs: Light 1 records 6V, light 2 records 3V, light 3 records 12V, light 4 records 3V, light 5 records 6V and a 12V power source. Which two lights must be selected and how should they be connected to the two poles of the power supply so that the two lights will light up normally? *

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.
