In a thin stainless steel rod a disturbance propagates with a velocity of 5000 m/s.
The steel shaft length is 1.25 m, therefore the total propagation time, to and fro, is 0.0005 sec.
Impact duration is however less, i.e., 0.0004 sec.

Never would have thought of that. But it makes perfect sense now.
Thanks!
