A motor exerts a constant force of (120 mathrm{~N}) tangential to the rim of a (20-mathrm{kg}) cylindrical
Question:
A motor exerts a constant force of \(120 \mathrm{~N}\) tangential to the rim of a \(20-\mathrm{kg}\) cylindrical flywheel of radius \(0.50 \mathrm{~m}\). The flywheel is free to rotate about an axis through its center and runs perpendicular to its face. If the flywheel is initially at rest and the motor is turned on for \(2.0 \mathrm{~s}\), how much work does the motor do on the flywheel?
