Homework Equations
Ac=((2pi*r/T)^2)/r
Where T is the time period
The Attempt at a Solution
Since a g is 9.8m/s^2
20(9.8)=(4*pi^2*29)/T^2
1144.87/(20(9.8))=5.841
And solved for T getting...
sqrt(5.841)=2.417
The book's answer at the back reads 0.749 revs/sec.
Did I miss something or is there something else I'm supposed to do with the answer? Thank you for your time.
