Griffin,

Post #33 in this thread has the calculations for this. The paragraph about an angled hit against the wall uses .94 m/s. The question for you is how much did the table/desk move when you bumped it ?

btw, I never turn my computers off. I let the energy saving sleep mode kick in. Then, all I need to do is hit the space bar to wake the computer and log in. Although one can, I don't password lock a sleep/awake log in so I just hit the Enter key.

I may do a full shut down once a month or so. Microsoft shuts down and restarts my computer more often than I do when Windows Update needs a reboot.

This would save you from needing to duck under the table/desk.
