Please mark brainliest you answer is B).
Have a good night!
Answer:
Explanation:
By multiplying the rotational frequency with the circumference we can determine the average speed of the object. The circular velocity formula is expressed as, vc = 2 πr / T. Where in, r denotes the radius of the circular orbit. T is time period.
A= v²/R
a = 12²/30 =4.8 m/s²
