Force causes an object to move in the same direction that the force is applied. Friction reduces efficiency<span> when two surfaces slide past each other, also </span>friction<span> resists their motion, and in </span>machines<span>, some input work is always used to overcome </span>friction<span>.

Answer:
0.89534 kgm²
Explanation:
= Final angular velocity = 12.9 rad/s
= Initial angular velocity = 5.5 rad/s
= Initial moment of inertia = 2.1 kgm²
= Final moment of inertia
As there is no external torque the angular momentum is conserved
The final moment of inertia is 0.89534 kgm²
