Hi, Compton yo!

Greetings and WELCOME to the site! I just moved your question that you had posted in Introductions to this forum topic area so that it would get the most exposure to those who are best able to answer it. Introductions is for people to introduce themselves and we try to not ask questions there.

It can be a little confusing when first learning how to use this site! Your question will get noticed much more in this forum area.

We would appreciate it if you would return to Introductions sometime to tell us a little about yourself though, if you would be willing to do that.

Concerning your question, have you checked out the instructions that can be found via clicking on the following link?

Thanks!

using s = ut + 1/2at^2

s = 0*1.4 + 1/2*9.81*1.4^2

= 0 + 9.6138

= 9.6138m -------- height from 2nd floor to 5th floor


Height of 5th floor from ground = 5.6 + 9.6138

= 15.2138m
