8. A certain merry-go-round is accelerated uniformly from rest and attains an angular speed of 1.2 rad/s in the first 18 seconds. If the net applied torque is 1200 N - m, what is the moment of inertia of the merry-go-round? A) 1400 kg m2 B) 18 000 kg m2 C) 9000 kg m² D) 500 kg m² E) This cannot be determined since the radius is not specified.
