Problem

A thin, uniform rod

0.80\,\text{m}

long rotates in a horizontal plane about its midpoint with a constant angular speed of

5.0\,\text{rad}\!/\!\text{s}

. At the instant the rod makes a

30^{\circ}

angle above the positive

x

-axis, what is the

x

-component of the velocity of the rod’s right-hand end? (Positive

x

is to the right.) (a)

+1.7\,\text{m}/\text{s}

(b)

+1.0\,\text{m}/\text{s}

(c)

-1.0\,\text{m}/\text{s}

(d)

-1.7\,\text{m}/\text{s}
