1. The problem statement, all variables and given/known data In a certain carnival ride, visitors enter a circular room with radius r=9.1m. The room then begins spinning around its center, reaching an angular speed of 1.7rad/s. What centripetal acceleration do the riders experience? 2. Relevant equations ac= v^2/r 3. The attempt at a solution I believed that ac= v^2/r which would equal .3175824176 or .32 m/s^2 but the answer is 26 m/s^2 and the explanation is Centripetal acceleration is given by ac=rω2. WHY?
