You have a horizontal grindstone $($a disk$)$ that is $88$ kg$,$ has a $0\mathrm{.}31$ m radius, is turning at $93$ rpm $($in the positive direction$),$ and you press a steel axe against the edge with a force of $16$ N in the radial direction.

What is the number of turns, N$,$ that the stone will make before coming to rest?

$$

What best describes the difference between these two kinds of acceleration?

There is no difference $$ they are two names for the same thing.Centripetal acceleration is along the edge of the circle, while tangential is towards the center.Centripetal acceleration is due to forces, whereas tangential is due to motion.Centripetal acceleration is towards the center, while tangential is along the edge of the circle.Tangential acceleration is always constant, while centripetal is always changing.Centripetal acceleration is always constant, while tangential is always changing.
