# Homework Help: Physics

Posted by Kinematics on Monday, January 14, 2013 at 6:52pm.

A carnival ferris wheel completes five turns about its horizontal axis every minute. What is the acceleration of a passenger at his/ her lowest point on the ride?

I understand that 1/f= T which is how you find the period and that minutes must be converted to sec, but I'm getting really strange answers for the centrip. acceleration. Is the question asking for the linear acceleration or both? Any help would be really appreciated!

we assume that the speed is constant so there is no linear acceleration, only centripetal.

We HAVE to know the radius.

T = 60 sec /5 turns = 12 seconds/turn

v = 2 pi r/T
and
Ac = v^2/r
