A particle starting from rest moves with constat acceleration 'a' and attains a velocity 'v' , then moves with uniform velocity 'v' for certain time and then decelerates at a constant rate 'b'. if 't' is the total time of motion, find the value of 'v' (in terms of a & b),so that 't' is minimum.

Last night there were big storms in the area. This morning, a bunch of outlets in one section weren't working. I had to flip the breakers off and then on again to restore power to the outlets. Any ideas on what happened here? Is there any specific damage I should look for? Appliances seem to be working, but I had to get to work this morning and didn't have time to check everything.

9 inches apart along a 3-foot long line, then turns 90° and buries acorns in a straight line for another 3 feet, and continues in this manner until he has completed a perfect square. Each side of the square is three feet long.

Can you figure out how many acorns Square Sam buries to complete his square?

I know, I know, just because it is impossible for the human brain to imagine the absence of space and time doesn't mean they can't not exist at some place and time.
