Problem

A uniform rod of length

0.80\,\text{m}

pivots about one end and starts from rest with a constant angular acceleration of

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

. After the rod has rotated through an angle of

0.40\,\text{rad}

, what is the linear speed of the point located at the rod’s midpoint? (a)

1.6\,\text{m/s}

(b)

2.0\,\text{m/s}

(c)

0.80\,\text{m/s}

(d)

0.60\,\text{m/s}
