A solid cylinder of masqttbm --)-uj oq9 s;tcoc(sv smb1)6ss 10 kg is pivoted about a fal 3l +dq2u xbux7h0w8rictionless axis thought the ceuudabw807l2x+ hlqx 3nter O. A rope wrapped around the 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. $10 \; rad$
