Ok this question is based upon a real life experience. I am in a vehicle on a relatively straight road that goes on for miles. My vehicle is traveling at a relative speed of 85 mph. I notice a vehicle in my rear-view mirror just enter the extreme range of that mirror's vision. I aproximately 5 seconds I was passed by this vehicle and was in the extreme range of my forward vision. The day was sunny and clear with no glare from the sun. How fast was this vehicle going relative to my observation point as driver of the vehicle going 85?

This car was moving so fast that I could not possitively identify and of it features every thing was a blur. I think that it was greyish. You can assume any relative distance between my vehicle and the two extreme ranges. I have perfect 20/20 vision if that helps. I just seem to be drawing a blank on how to approach this problem. It's not urgent just bugs me.

Sometimes I will look up at a digital clock to see the number 28. This happens during the day and at night. I car will pass by and I will see the number 28 on its tag and have even noticed that sometimes a call will come throught on my cell at 28 on the hour. i.e. 12:28, 2:28 and so on. My birthday in on 9/28. I only just started noticing this within the last year. I'm not one to believe in "hocus pocus" stuff but I can't help but notice this number thing going on all the time. Anyone else have this happen to them?

Obviously their is nothing in Space. That is why its called Space. All the poisionous gases in Space ,their can't possibly be any form of life., and besides we have all the resources we need here on Earth.

The UK is supposed to be battered tonight by the worst storm of the year. It could be close to a hurricane as it gets here with winds over 80mph. What will you be doing to keep safe?

i hav the mass of an object which is 560,000 kg
i have the speed of the same object in m/s = 250 m/s
and i need to find the Pressure in Pascals
i know that Pressure = Force / Area
and Pressure = mass / length x time^2

is it correct if i do this-
Pressure = mass / length x time^2
Pressure = kg / ms^2
or Pressure = kg / [(ms^-1) x s^3]
therefore Pressure = 560,000 / 250 x (1^3)

i have assumed that since speed of object is 250 metres per second, s = 1 second, and therefore s^3 = 1^3 = 1
therefore Pressure = 560,000 / 250
= 2240 Pa or 2240 N/m^2 in other word 2240 kg/ms^2
is this correct?
i wud appreciate an explanation if it is or if it isn't

As my birthday approaches I start to collect leaves - a little bizarre perhaps, but I enjoy it! On the first day of the month I collect one leaf, on the second day I collect two and so on. So by my birthday I will have collected 276 leaves altogether. On which day of the month is my birthday?
