- •
A statistical criterion of the three post-impact motion features is presented.
- •
Two critical angles are linear to impact velocity.
- •
Two critical angles have different scaling relation with system variables.
- •
Force's intermittent time and magnitude are direct consequence of acoustic pulses.
