force of gravity in x direction...?...0 ofcrse....
and force of friction....will be 200*(g-4)
do check the answers

Answer 4

yay! youre really good at this! :)

Answer 5

thnks....but did u get it...?

Answer 6

it doesnt tell me if its the correct answer or not but when i solved it, i got the same answers!

im just a little iffy about fgx but i think its just 0

Answer 8

hey...remember vectors...? a vector can't have a resolved part in a direction perpendicular to it....?...its jst dat...g acts in y direction...it cant have a part of it in x direction..meaning perp dircn...so accn=0...force=0...sorry for late reply...an idiot called me...
