An object is traveling around a circle with a radius of 20 meters. if in 10 seconds a central angle of 1/5 radian is swept out, what is the linear speed of the object?

The linear speed is 0.4 m/s

Step-by-step explanation:

Given,

The radius of the circle = 20 meters,

The central angle made by the object that travelling around the circle = radian,

So, the distance covered by the object = The radius of the circle × Central angle made by the object ( in radians )

Now, the time taken by the object in travelling = 10 seconds,

Hence, the linear speed of the object =

= 0.4 m/s

not sure but it may be b, as i said i'm not sure.
