Linear speed $\"\"$ of the object is $\"\"$ , where $\"\"$ is the distance travelled in time $\"\"$ .

\

Angular speed $\"\"$ of the object is $\"\"$ , where angle $\"\"$ (measured in radians) swept out, divided by the elapsed time $\"\"$ .

\

Find the angular speed of the object.

\

Radius of the circle $\"\"$ centimeters.

\

Central angle $\"\"$ radian.

\

Elapsed time $\"\"$ seconds.

\

Angular speed $\"\"$ of the object is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in above formula.

\

$\"\"$

\

Thus, the angular speed of the object is $\"\"$ radian/second.

\

\

Find the linear speed.

\

Linear speed $\"\"$ of the object is $\"\"$ .

\

Length of the arc $\"\"$ .

\

$\"\"$

\

Length of the arc is 1.67 centimeters.

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Thus, the linear speed of the object is $\"\"$ centimeter/second.

\

\

The angular speed of the object is $\"\"$ radian/second.

\

The linear speed of the object is $\"\"$ centimeter/second.
