Has this happened to you?

....you're headed towards the bathroom, and you have about 8-10 feet before you get to the door, which swings in (that means you push it)...you've been here before so you know it's a multiple stall/urinal type, the door won't be locked.  As you approach you see the door open up and someone walks out.  There are different scenarios to this event, sometimes they will hold the door for you to enter, and sometimes they- won't.

Today I experienced the latter, the door was not held, as I was still the previously mentioned 8-10 feet away.

I had options on what to do, everyday we all have choices and we live with the consequences, whatever they may be.  This day and this choice was no different.

• continue at the same pace, because of the exiting party there could be an awkward moment where you may need to take evasive action to avoid collision.  The door will not fully close, and you'll be able to enter with less force to open the door.
• slow down to give a wide birth to the exiting party, this will usually cause them to take evasive action to avoid collision considering the location of the doorway.  This may result in the door fully closing which will require you to open it fully to enter.
• increase speed to catch the door before it closes, this may allow you to squeeze through the doorway without having to touch the door (Lord knows how much bacteria is on there)  Considering your surroundings, this may be a dorky move.
• Take caution as someone may be exiting the Ladies room at the same time, this can cause a major incident.

So having these three options, I took several factors into account.  Who was exiting, how much time did I have, with the sudden rush of speed use more energy then it would take to push open the door?  This got me thinking which way was more efficient.  Force vs inertia.  wind resistance, the weight of the door, the weight of me...my current velocity...what to make for dinner...

...I really hate math....

so I ended up with option three, and did a little hop through the door...no one was injured

If anyone can tell me the correct calculation to determine the answers to these kind of questions, I'd appreciate it.
