The acceleration is proviced by the rotating wheel, and more importantly, whatever is holding the rider in place. That force is accelerating the rider inward.
a. v=2PIr/period=6.28*2/.9 how exactly did you get 141?
b. centacceleratio= v^2/r
The carnival ride shown in Figure 7-18 has a 2.0 m radius and rotates once each .90 s
a. Find the speed of the rider.
b. Find the centripetal acceleration of the rider.
c. What produces this acceleration?
SOLUTIONS PROVIDED:
a. 141
b. 98
c. --Explain--
Completely stuck and I don't get the answer in any way.

An answer key provided, although I was in a bit of a rush so I could have possibly copied the answer down wrong...
she could have meant 14.1... just saying
a ) it is 2 *pi *2/0.9 = 13.9 m/s
b) 13.9ˆ2 /2 = 96,6 m/sˆ2 Correct?
b) 13.9ˆ2 /2 = 96,6 m/sˆ2 Correct?
