A 69cmdiameter wheel accelerates uniformly about its center from 150rpm to 320rpm in 4.4s . Determine angular acceleration?

change in rpm = 170
170 rev/min *1 min/60 s * 2 pi radians/rev = 17.8 radians/second change
which is delta omega
alpha = change in omega/ change in time
17.8 radians/second / 4.4 seconds
= 4.05 radians/second^2
