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

mass and radius are spurious information
convert 33.5 rpm to rad/s ... multiply by π and divide by 60
... divide by 2 to find average angular velocity during acceleration
convert 240º to radians ... multiply by π and divide by 360
... divide result by average angular velocity to find acceleration time
acceleration is max velocity divided by acceleration time

u mean
(33.5*3.142)/60=1.75
Then
1.7/2=0878(angular velocity)
(33.5*3.142)/60=1.75
Then
1.7/2=0878(angular velocity)
