- to calculate the centripetal acceleration, you need to know the radius and the period of the carousel.

to find the circumference of the outer horses on the carousel you must measure the distance between 2 poles then multiply that to the total number of spaces between the horses, but to calculate the circumference for the inner circle you have to repeat the process because its smaller which means a smaller circumference.
