A rope is wound around a hollow cylinder of mass $3\text{kg}$ and radius $40\text{cm}$. What is the angular acceleration of the cylinder if the rope is pulled with a force of $30\text{N}$?

1. A
   $0.25{\text{rad/s}}^2$
2. B
   $25{\text{rad/s}}^2$
3. C
   $5{\text{m/s}}^2$
4. D
   $25{\text{m/s}}^2$
