If you have a choice, what do you prefer?

  1. take a hit from a tiny steel ball weighing 1/2 kg at 200km/sec or a large steel ball weighing 1000kg at 0.1km/sec
  2. take a hit from a tiny rubber ball weighing 1/2 kg at 200km/sec or a large steel ball weighing 1000kg at 0.1km/sec
  3. an object pressing against your skin or an object that has time and distance to travel to make an impact
  4. take a structured hit versus hit from an light object traveling at high speed
  5. take it from a sharp object or a blunt object

Exercise:
Think through each of the above. Hope you find there is more to it than what is obvious. Discuss your choice, assumptions, thresholds and exceptions. (Give examples if possible)
