Hi again, I'm sorry for all of the questions in this section. I am having the worst time trying to understand how to set up the problems. I know the equation for acceleration is a= V^2/r; however for this problem I am looking to find the velocity and time. Again, I would appreciate any kind of help possible. What are the period and speed of a person on a carousel if the person has an acceleration with a magnitude of 0.7 m/s2 when she is standing 3.8 m from the axis? What are her acceleration magnitude and speed if she then moves to a distance of 2.1 m from the carousel center and the carousel keeps rotating with the same period? Thank you!
