Question

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

Answer 1

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

Answer 2

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

Answer 3

Please is that the answer
