Question

An object is swung in a circle with the radius of 5 m. If the object makes one rotation in 2.2 sec, what is the velocity of the object?

Answer 1

14.28 m/s

Step-by-step explanation:

We use this equation to find ciruclar velocity: v = 2πr/T

Find your given:

r = 5 m

T = 2.2 s

Plug in your given into the equation:

v = 2π(5 m)/2.2 s

v = 14.28 m/s
