Angular Acceleration of a phonograph turntable?
A phonograph turntable reaches its speed of 33 rpm after making 1.7 revolutions. What was its angular acceleration?
I know how to do this problem when a time is given, but not when they provide how many revolutions it took to reach the 33 rpm.
It's the same problem as with linear acceleration, and has the same working formulae
v^2 = u^2 +2as
where v = final velocity or angular rotational rate
u = initial velocity or angular rotational rate
a = acceleration (linear or angular)
s = distance or angle turned
