F minus f equals M a minus negative negative negative negative negative negative left parenthesis 1 right parenthesis
A s space w e space k n o w space f
o r space p u r e space r o l l i n g
a equals alpha R minus negative negative negative negative left parenthesis 2 right parenthesis
F o r space t o r q u e
f R equals I alpha
f R equals fraction numerator 2 M R squared over denominator 5 end fraction alpha
alpha equals fraction numerator 5 f over denominator 2 M R end fraction minus negative negative negative negative negative negative negative left parenthesis 3 right parenthesis
a equals fraction numerator 5 f over denominator 2 M R end fraction R
a equals fraction numerator 5 f over denominator 2 M end fraction
S u b s t i t u t i n g space e q u a t i o n space 3 space i n space 1 space w e space g e t
F minus f equals fraction numerator 5 f M over denominator 2 M end fraction
f equals fraction numerator 2 F over denominator 7 end fraction
