(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A circle with radius 2 cm rotates at 1000 rpm and the acceleration at the rim is 2 ms^{-2}.

a. What is the acceleration at the center ?

b. What is the acceleration at 1 cm from the center ?

2. Relevant equations

3. The attempt at a solution

a. The acceleration will be zero because the center doesn't move?

b. a = ω^{2}r = 2πf*r = 2π * 1000/60 * 2 x 10^{-2}= 2/3 π ms^{-2}. Is this right?

Thanks
