[SOLVED] "webassign" problem, CENTRIPETAL ACCEL
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?
4*pi*R(radius) / T^2
where T=time
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 don't see how!
EDIT: also, is there a difference between the magnitude of centripetal acceleration as opposed to mere centripetal acceleration?
