What was the dependent variable (the variable that changed because of the independent variable) in this investigation? How was it measured? Include the units in your answer. The variables Car 1 3.64 3.54 3.69 Car 2 3.24 3.47 3.36 Meters Each car traveled 2.5

This is the answer: body 1 + engine 2

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.

Athermometer to measure the temperature of course
