A solid cylinder of massi6/9c5ctujdn 10 kg is pivoted about a frictiom5,j t i5u-z iae7pxj/nless axis thought the center O. A rope wrapped around ,5aiux-j p emitz/5 7jthe outer radius $R_1$ = 1.0 m, exerts a force $F_1$ = 5.0 N to the right. A second rope wrapped around another section of radius $R_2$ = 0.50 m exerts a force $F_2$ = 6.0 N downward. (figure below) How many radians does the cylinder rotate through in the first 5.0 seconds, if it starts from rest?

A. $13 \; rad$
B. $7.5 \; rad$
C. $5.0 \; rad$
D. $10 \; rad$
