So I have this lab where one of the questions asks to find the average acceleration (m/s^2)
The formula is a=v2-v1/change in time
I don’t understand how to solve this since I only have the average time and distance in (m) for the marble

  1. your distance is your average speed * time
    if your marble started at a stop then V1 = 0
    then v = a t
    x = (1/2) a t^2
    a = 2x/t^2
