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. Also given (if needed): Net applied torque is 1200 Nm Moment of inertia is 18181 kg•m^2 Kinetic Energy is 13090 J Assuming friction is negligible, how much work does the motor have to do to accelerate the merry go round up to 1.2 rad/s? How much power does the motor have to generate to accelerate the merry...
