A 1.0-ft by 3.0-ft section of a wall is made up of a 2.0 in layer of concrete and a 3.0 in layer of white pine. If the inside temperature is 60 °F and the outside temperature is 25 °F, what is the heat flow rate for this section of the wall? Enter your answer to two significant figures without units.

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.
