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 car’s 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?

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
