Problem

A uniform thin rod of length

1.0\,\text{m}

and mass

2.0\,\text{kg}

is pivoted about one end and is free to rotate in a vertical plane. Ignoring gravity, a

25\,\text{N}

force is applied perpendicular to the rod at its free end. What is the resulting angular acceleration of the rod? (a)

19\,\text{rad/s}^2

(b)

38\,\text{rad/s}^2

(c)

13\,\text{rad/s}^2

(d)

150\,\text{rad/s}^2
