You are sledding with your friends and need to make a 48 kg sled travel at a speed of 9.0 m/s. However, you can only apply a maximum 280 N of force. How far do you have to push the sled before it reaches that speed? Assume a frictionless icy surface. Group of answer choices

14 m

0.77 m

1900 m

6.9 m

430 m

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.
