Answer:
The linear speed is 6.51 m/s
Explanation:
Uniform Circular Motion
It's a movement of an object along the circumference of a circle. It can also be defined as a rotation along a circular path.
The angular speed can be calculated as follows:
[tex]\displaystyle \omega=\frac{v}{r}[/tex]
Where:
v = tangential or linear speed
r = radius of the circle described by the rotating object
To calculate the linear speed, solve for v:
[tex]v = \omega\cdot r[/tex]
[tex]v = 21\ rad/s\cdot 0.31\ m[/tex]
[tex]v = 6.51\ m/s[/tex]
The linear speed is 6.51 m/s
