Consult multiple concept example 10 in preparation for this problem. traveling at a speed of 18.2 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. the coefficient of kinetic friction between the tires and the road is 0.590. what is the speed of the automobile after 1.43 s have elapsed?

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.
