Grey decides to take his jet ski out for a spin. He first skis 6 meters south and then turns west and skis 8 meters. What is Grey’s distance from the dock? What is his displace to from the dock? Make sure to show all your work and provide proper units and direction. Finally, determine which measure to is a vector quantity and which is a scalar quantity.

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.
