A sculptor is sharpening a chisel on grindstone of radius 1.0 m that is spinning with a constant angular speed of 2.0 rad/s.
-What is the magnitude of the centripetal acceleration of a point on the rim of the grindstone?

Question

Quizplus · Accepted Answer

The centripetal acceleration is given by the formula $ a_c = \omega^2 \times r $, where $ \omega = 2.0 \, \text{rad/s} $ and $ r = 1.0 \, \text{m} $. Thus, $ a_c = (2.0)^2 \times 1.0 = 4.0 \, \text{m/s}^2 $.
