Hi im just starting a college physics class, all the work is pretty much online and im am having a terrible time learning all the equations and things of that nature. The question is
You are standing by your living room window when an object falls vertically downward in front of you. You observe that it takes 0.210 seconds for the object to pass the window, which is 1.35 m tall. From what height did the object fall from above the window?
I know that the object is experiencing 9.8 m/s in freefall but i have no clue where to start as far as equations go. Please help im terrible at this.
