G An object spins in place with no unbalanced forces or torques acting upon it, what do we expect this object to do? The object’s spin will slow and eventually reverse direction. The object will continue spinning as it has been. The object will spin faster and faster. The object will begin to roll. None of these answers. The object will slowly stop spinning.

The object will continue spinning as it has been.

Explanation:

When an object is spinning in a closed system with no unbalance

forces and no external force or torques are applied to it, it will have no change in angular momentum.

According to the law of conservation of angular momentum which states that when no external torque acts on an object, no change of angular momentum will occur

If the change in angular momentum is zero, then the angular momentum is constant; therefore, the object will continue spinning as it has been.

The same scenario is applicable to the rotation and the spinning of the earth.

speed = 20/2 = 10 m/s
