It takes a bus driver 30 min to pick up students from four stops. the last stop is at the corner of green street and route 70. the most direct route to school is north on route 70. the speed limit on route 70 is 35 kph. the bus driver wants to calculate the average velocity from the last stop to school. can this be done from the information given?

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.
