Information challenge – force of a kangaroo punch

[Lang]

My two bobs worth on this stop the presses subject is:

As mentioned, kangaroos do not punch in the wild (I watch them out my back window every morning). As stated they grapple to set up a hind-foot kick almost never seriously injurious to their opponent. This happens daily in the human-like disputes over women or a particularly juicy patch of grass. By far the most common fight is when the two bucks stand chest to chest on tip-toe to gain impressive height and start slapping each other like two patrons in a gay bar dispute. A long fight is two minutes.

Showmen over the years have fitted them with gloves but the strikes are of a flapping/slapping motion never a straight right or a left hook.

I suggest you lay your head on the kitchen scales and have your wife give you a " moderately naughty boy" smack across the ear. The measured deflection of the dial would be a pretty close measurement of the energy of a kangaroo "punch".

Any size kangaroo.
Using forefeet or hind feet.

The question from a library patron was not that specific so lets assume the worst or hardest hit possible.

If you are wondering this is what librarians talk about after a long hard week after the second glass of wine.
