Answer:
During the moment when she grabs the swing is conserved the angular momentum and the energy.
Explanation:
The external torques in a system change the momentum or:
Where dl is the change in the angular momentum, dt the change in the time and T the torque.
So, if the external torques is equal to zero, the mometum is conserved. In this case, there are not external torques in the system therefore the momentum is conserved.
On the other hand, the energy is conserved when there aren't no conservative forces in the system, like friction, so, in this case if we ignore the air resistance the energy is conserved.
