Answer:

21s

Step-by-step explanation:

Given parameters;

Radius = 10m

Speed or velocity = 3m/s

Unknown:

Period = ?

Solution:

To solve this problem, use the expression:

v =
(2\pi r)/(T)

r is the radius

T is the unknown

Input the parameters and solve for T;

3 =
(2 x \pi x 10)/(T)

62.84 = 3T

T = 21s
