Homework Statement
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 ?
Homework Equations
The Attempt at a Solution
a. The acceleration will be zero because the center doesn't move?
b. a = ω2r = 2πf*r = 2π * 1000/60 * 2 x 10-2 = 2/3 π ms-2. Is this right?
Thanks
