This problem involves torque and acceleration.
where I is the moment of inertia.
Moment of inertia of a disk:
where R is the radius of the disk.
A merry-go-round accelerates from rest to 0.69 rad/s in 25 s .
Assuming the merry-go-round is a uniform disk of radius 7.1 m and mass 32000 kg , calculate the net torque required to accelerate it.
