Physics and mathematics are something i use all the time. You cannot argue with them! Though I also use statistics and I can say the following - you give me the value you want to get I will arrive there, with a proof!GMTURBO43 said:Haha - something I can actually use physics for.
No you can not!Mevi88 said:Wait -
So I can't just use Distance = Rate x Time
0.2 miles = rate x 0.0017 hours
(6.25 seconds to go from 0 to 50- according to the previous calculations)
Rate = 117.6 miles/hour
So, wouldn't that be almost impossible?
How about getting in the MO, reset the trip hit the gas and see how fast you are when you hit .2 miles? Just a thought.Mevi88 said:Well, I got a speeding ticket pulling out of my condo complex last Friday.. they said I was going 50mph.. and the distance was less than 0.2 miles... I am trying to figure out if I can use some math in court to get out of my ticket!! I really don't think I was going 50.. but you know the Murano.. you step on the gas and it just goes.. I'm sorry officer!
Thanks for your help.
Well put. Even without those calculations, its easy to figure out that if the Murano can do the quarter mile in [email protected], it can definitely get up to 50 in .2 miles.CP-Mike said:Okay, so if you are having trouble believing the 0.04-miles-to-get-to-50 figure, consider this.
We can solve for the acceleration necessary to get to 50 mph in 0.2 miles by rewriting the equation to a = (Vf^2 - Vi^2)/(2*d) and plugging in 50 mph (0.01388 mi/sec) for Vf, 0 for Vi, and 0.2 mi for d. The result is that a = 5.36x10^-4 mi/sec^2.
Now take that and plug into Vf = Vi + a*t and solve for t, the maximum amount of time you can take to get to 50 mph in 0.2 miles. This comes out to be 25.9 seconds.
Now this test is a lot easier: Can you get your MO up to 50 mph in 25 seconds? I think if you were actually trying and still unable to do that, you must have some very serious issues... 25 seconds is a long time.
