Yes, MECHANICA does one time impact loading. And No, Dynamic Shock is not necessarily what you are looking for. Search "Dynamic Time" and you will find the ability to apply a sine wave load - applied one time, over the time span you want.
AND - in the "rigid body" world, you will find MDO (Mechanism Dynamics Option) will allow you to do the same thing to a "system" of rigid bodies, connected together with springs and dampers.
It all depends on what you are looking for as "output" as to which application / solution you need.
