3. ## Re: Calculus Is Fun

5. ## Re: Calculus Is Fun

There is an error in Q2:
it's should be its.

Otherwise, I have nothing to add to Hans' masterly erudition!

6. ## Re: Calculus Is Fun

A better formula for use in Q2 is:

v(f)² = v(i)² + 2ad where f and i are final and initial states, d is the distance travelled. So

v(f)² = 22² + 2 x 32 x 108 = 7396

=> v(f) = 86

But it does! A bad cook will try to follow the recipe to the letter and make a mess, a good cook will ignore or change the bad parts and come up with something nice...
