We have inelastic impacts between a ball and a person. The ball is moving and the human is in rest. It hits him first in his Center of mass. In this part question it is imagined that the human stands on ice and he (gets pushed without friction .. yea i know but as i said idealize!) such that we can imply the conversation of momentum.
the part which confused me is this
What happens when the ball hits ABOVE the Center of mass?
So i thought well, maybe the ball will cause a Torque on the horizontal axis of rotation of this human since it is changing its Momentum and we know that the change of momentum / time = force and the distance $d$ where teh ball hits from the Center of mass will give us our Torque $d * F$
