Let us say you are working in a crash test facility. The car you are testing hits the wall, the dummy is slumped over the wheel, and broken glass is everywhere. There is just one problem: your radar that measures the carâs speed was turned off!
You know that the length of your track is 15 meters. You also know that the car crossed the entire track in 0.5 second, because your high-speed cameras recorded the entire event. Use that information to answer the questions below.
What was the average velocity of the car during its test on the track?
As usual, any non-answers will be reported. Thank you!

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 ”n on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in ”n.)
