   Is the length of time for which an object is falling directly proportional to the force it hits the ground with?

   The speed of a falling object is proportional to time (assuming no air resistance) V=u+gt
   
   The force it hits the ground with depends on how quickly it stops.
   But if we assume the stopping time is the same then F=ma and a (deceleration) is speed/stopping time
   
   So yes.

   In the context of things falling close to the Earth's surface, yes.
