Expert Answer:

f left parenthesis x right parenthesis space equals space m g sin theta minus mu subscript 0 x m g cos theta
I n i t i a l l y space t h e space v a l u e space o f space x equals 0 space s o space n e t space f o r c e space w i l l space b e space m g sin theta space a n d space v e l o c i t y space i n c r e a s e s. space A s space x space i n c r e a s e s space t h e space n e t space f o r c e space w i l l space b e g i n space t o space d e c r e a s e. space
B u t space d u e space t o space n e t space f o r c e space i n space d o w n w a r d space d i r e c t i o n space t h e space v e l o c i t y space k e e p space o n space i n c r e a sin g space t i l l space n e t space f o r c e space w i l l space b e c o m e space z e r o.
f left parenthesis x right parenthesis equals 0
m g sin theta minus mu subscript 0 x m g cos theta equals 0
x equals fraction numerator tan theta over denominator mu subscript 0 end fraction
