[SOLVED] "webassign" problem, CENTRIPETAL ACCEL 1. The problem statement, all variables and given/known data The Emerald Suite, a revolving restaurant at the top of the Space Needle in Seattle, Washington, makes a complete turn once every hour. What is the magnitude of the centripetal acceleration of the customer sitting 14.5 m from the restaurant's center? 2. Relevant equations 4*pi*R(radius) / T^2 where T=time 3. The attempt at a solution so then it would be 4*pi*14.5/3600^2, which gives me: 1.41E-5 but it's showing me that its incorrect...but i dont see how! EDIT: also, is there a difference between the magnitude of centripetal acceleration as opposed to mere centripetal acceleration?
