A rotating turntable of mass 200g and

radius 10 cm is uniformly accelerated from rest to attain
it's maximum velocity of 33 and half revolution per
minute through an angular displacement of 240 degree .
Determine the (1). uniform angular acceleration. (2).time
of acceleration

So I did this. Help me confirm

33.5*3.142)/60=1.75
Then
1.7/2=0878(angular acceleration )
