Kinematics: Basic Homework Question on Cop and Car

Oh yea, I remember that from a certain calculus teacher.

The derivative of distance over time is velocity, the derivative of velocity over time is acceleration, and the derivative of acceleration over time is jerk!

I just did the problem myself and it took me about 20 mins...and that's only part a

This is NOT a basic kinematics problem...

That or my brain is getting rusty from pure math lol.

Well it's pretty linear (without calculus - did u try it with calculus?), a little long but not too long and/or difficult IMO.

I remember "jerk" from XKCD!

Honestly it's even more difficult to use calculus to this problem
