Help determining initial velocity

[valdez237]

im working on a lab and i have to determine the initial velocity of gliders that we pushed down an airtrack. the only data that was recorded is the change in x and time.

eg.
change in x = .3 meters
t= 1.1 seconds


i've looked through all the equations i could think of to find the answer to this, but they all require more than one variable. if i could even get the slightest bit of help that would be amazing.

Which quantity is represented by the slop of x-t graph?

I can suggest using the equation v = Δx/Δt to determine the initial velocity of the gliders. In this case, Δx represents the change in position or distance traveled and Δt represents the change in time. Therefore, the initial velocity can be calculated by dividing the change in position by the change in time. In this scenario, the initial velocity would be 0.3 meters divided by 1.1 seconds, which equals approximately 0.27 meters per second.

It is important to note that this equation assumes constant velocity, meaning that the gliders were traveling at a constant speed throughout their entire motion. If the gliders were accelerating or decelerating, a different equation would need to be used. Additionally, it is always best to have more data points and variables in order to accurately determine the initial velocity.
