    A pulley of radius 1.5 m1.5\text{ }m is rotated about its axis by a force F=(12t−3t2)NF =\left( 12t - 3t^{2} \right)N applied tangentially (while tt is measured in seconds). If moment of inertia of the pulley about its axis of rotation is 4.5 kg m24.5\text{ }kg{\text{ }m}^{2}, the number of rotations made by the pulley before its direction of motion is reversed, will be Kπ\frac{K}{\pi}. The value of KK is
