Homework Statement
a grinding wheel 0.5 m in diameter roates at a rate of 8.00 x 10^2 revolutions per minute. find the magnitude of the acceleration of a speck of metal cuaght in the outer edge of the wheel
Homework Equations
a=4pi^2r/T^2
[/B]
The Attempt at a Solution
I was wondering if i used the right equation?
To get T (time for one revolution) i divided 60 seconds by 800 revolutions .I plugged that into my equation for acceleration along with .25 m radius. The answer i get is 1750 m/s^2
