i found my mistake here :).........don't worry about the g .......g cancel out from equation ;)
12) is same as 11)......the only difference is u have to find initial speed instead of angle :)........if u don't understand than i can explain u :)

I LOVE YOU lol


just one doubt

why did we use -0.5 and 3.5

why not use 0.5 as positive and keep 3.5 as 4

will we get the same answer?
