A cylinder is 0.10 m in radius and 0.20 m in length. Its rotational inertia, about the cylinder axis on which it is mounted, is 0.020 kg * m². A string is wound around the cylinder and pulled with a force of 2.0 N. The angular acceleration of the cylinder is:
a. 5.0 rad/s²
b. 15 rad/s²
c. 10 rad/s²
d. 20 rad/s²
e. 2.5 rad/s²
