Mass of the turntable = m
Diameter of the turntable = D = 68 cm = 0.68 m
Radius of the turntable = R = D/2 = 0.68/2 = 0.34 m
Moment of inertia of the turntable = I
The turntable is made in the shape of a solid disk therefore,
Angular speed of the turntable = = 35 rpm = 35 x (2/60) rad/s = 3.665 rad/s
Kinetic energy of the turntable = E = 0.29 J
m = 0.747 kg
Mass of the turntable = 0.747 kg
