1. The problem statement, all variables and given/known data 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-- 2. Relevant equations ac=v^2/r T=1/f Fc=m(4pi^2r/T^2) 3. The attempt at a solution I apologize for not using script, I was having a bit of difficulty. However, this is what I got. .90=v^2/2 √v =1.34 Completely wrong, please help.
