You could represent most of the 'physical' things in a mud as forces
(collisions, tensions, strains and stresses, etc), but would probably find
it useful to also take energy into consideration - ie: calculating the
energy a player has from food (etc), and using it up as (s)he moves around
carrying heavy gear.
Kinetic energy probably has fairly little to do with the penetration power
of a weapon (although linked to it via forces, and such, its not directly
involved, really). Force of impact, and angle of incidence (as well as
stress/strain considerations) are more important for suchlike.

Watts? Use something like N/m (newtons per m^2) and work with forces for
collisions, rather than in power (which is a rather abstract concept to
the immediate aim). Do conversions to energy later. You could do this, but
it would be far from a simple model. :)

Not a particularly easy task, is the short answer, although worthy of
consideration. :)

I tried once, and gave up, having botched embarrasingly badly.
According to my (mis)calculations, the arrow in the example figures would
strike a target 100 metres away with a net collision force of 3N. 3N being
equal to the force exerted by a 300g mass in earth's gravity. To quote
someone whom I have forgotten, "I think.. not."
