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.
Answer: As you already know people have cloned dolly sheep but what about people? will we be able to clone ourselves one day?. Good question, actually scientist believe it may be possible years from now, though it wouldn't be right if we didn't research. It is hard to clone animals let alone people which is probably one of the reason's some human's oppose it so much. Think of it this way though if we cloned ourselves or someone clones us after we die it'll be like we never left. It will bring less heart-ship to people knowing can always have that person. it will also make life more evolved in evolution and theory.
i couldn't think of anything else but her's a start :)

Energy at top = m*g*height at top from release point
=0.16*9.81*11.6
=18.21J
At release kinetic energy= Gravtiational energy at top
1/2*0.16*v^2=18.21J
v^2=227.625
v=15.10m/s
