MHB Mechanics- general motion in a straight line

AI Thread Summary
The discussion focuses on calculating the derivative of the motion equation s = 4t^2 - √(2t^3). Participants confirm the use of calculus, particularly derivatives, to find the velocity as ds/dt = 8t - (3√(2t))/2. A quadratic equation is derived from the calculations, leading to the conclusion that t equals 2s. The conversation emphasizes the importance of understanding derivatives in solving motion problems. Overall, the participants successfully navigate the calculus involved in the motion equation.

I don't know how to calculate this. Pls help

$s = 4t^2 - \sqrt{2t^3}$

have you learned any calculus, specifically derivatives?

Yeah so ds/dt=8t-3sqroot(2t)/2

I have tried doing this so ds/dt=v
13= 8t-3sqroot (2t)/2

So I get quadratic equation. I got t=2s. Thank you very much!
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
