The Attempt at a Solution
Here is what i have done so far:
Fx = cos 45 T - Ff =ma
Fy=sin 45 T -mg+ Fn =ma
I found ff= uk * Fn = 0.5 *sin 45 +mg
fn = sin 45 +mg
Isolated for T in the x and y:
Tx = ma + Ff / cos 45 = 13.404
Ty = ma +mg - Fn / sin 45 = 83.938
found the resultant for T: sqrt( (13.404)^2 + (83.938)^2 ) = 85 N????
What am i doing wrong? i've been stuck on this for 3 +hours now with no help :(
the answer is meant to be E.
