**Elena**, Monday, October 8, 2012 at 5:30pmR=v₀•t

t=R/v₀

197 rpm = 197/60 =3.28 rev/s

300 = 5 rev/s

ω=ω₀+εt

ε= (ω-ω₀)/t =(5-3.28)/22.5=0.0076 rad/s

a = ε•R=0.0076•0.63=0.0048 m/s²

**wally**, Monday, December 10, 2012 at 10:09pmyou forgot to convert form from frequency to angular velocity where

197rpm=3.28rev/s*2pi

apart from that the steps are accurate
