Sven, a wise man and a big time bet taker, was walking along when he came across Tommy. Sven wanted to make a quick buck so he said to Tommy, "I bet you $4,500 that you won't be able to stop accelerating in your car, after 10 seconds to get up to speed, on this circular track."
"Well, Sven, I'll take that bet. I just hope you don't cry too hard when I take your money."
So Tommy got his brand new red Porsche up to 90 mph and put it on cruise control. After four laps, he came up to Sven and paid him the $4,500. Why?

Hint
What shape was the track?Answer
First of all, Sven said accelerate. Acceleration is a change in velocity. Velocity is a speed in a direction. So acceleration can be speeding up, slowing down, or turning. Since the track was circular, Tommy was always accelerating, even after the ten second grace period. The lesson: know your terms before you take a bet.Hide Hint Show Hint Hide Answer Show Answer

Thats A Tuffiie ,, Cuuz Im In Year 7 That Was Harrrddd 4mmeee LOL x
well done! learned this last year
Wow.. I was never good at science.. probably cause I haven't really learned it since Grade 3
But couldn't Tommy have braked his car, and then it would stop, meaning it wouldn't accelerate?
Oh, and how do you hand someone $4,500 instantly?

Using CC would automatically mean the car would slow or reduce its speed, never reaching the time limit of ten seconds.
Better than I could do, good teaser

Good job!!
Good one! I didn't get the answer, but you explained very nicely. Then I got it.
EEEEEEEEEEEEAAAAAAAAAAAAASSSSSSSSSSSYYYYYYYYYYY!! but fun!
Very nice!
Wow! I should be careful when using the word 'accelerate' next time.
Angular acceleration
Terrific teaser. Easy if you know your science (fitting the category). Informative example of the definition of accelerate if you don't.
So what is the term for a change in speed? Does accelerate apply to both speed and velocity?
