i need physics help with this question??

A point on an object starting from rest and rotating with constant angular acceleration has a centripetal acceleration of 2.0 m/s^2 in magnitude. find the centripetal acceleration of the same point 6.0 seconds later

17.
Now - that may not seem funny but if you've ever seen the South Park "Awsome-O" 2000 episode, they ask him a question about wood chucks chucking wood and he answers.."17"....like I say, may not seem funny now but someday someone will ask you a similar question and if you don't know the answer...just say "17"...it's trending!

@luctoretemergo that is funny

I'm confused. The formula for centripetal acceleration is v^2/r. If the object is at rest, then v = 0, and so it seems to me that the centripetal acceleration would initially be 0 rather than 2. Is there any more to the problem than what you have stated here?

@DrWatson no that was all

@Candypie2010 In that case, I am as stumped as you are. Sorry. (If you do eventually find the solution, please let me know about it.)
