hi i have a project to make a step by step tutorial on how to build a computer can i get help?

YO are you vlad from my geometry class, mr. schwaigoffer

I see what is if i try to assume data results, based on prior knowledge is that possible if so how would i do that can you please point me in the right direction. Thank you very much appreciate it.

Assuming you mean 18.1 cm. x = at^2/2 ==> t = sqrt(2x/a) a = g = 9.81 m/s^2 2x = 0.362 t = 0.1921 s. it is right but you enter 18.2 ok

I am also in the VASTS program.My data is different, but they have the same concept.
