Question

An ordinary workshop grindstone has a radius of 7.50 cm and rotates at 6500 rev/min. (a) Calculate the magnitude of the centripetal acceleration at its edge in meters per second squared and convert it to multiples of $g$. (b) What is the linear speed of a point on its edge?

Final Answer

- $3.47 \times 10^{4}\textrm{ m/s}^2$

$3500 \textrm{ g's}$ - $51.1 \textrm{ m/s}$
