Answer: is 60
Since it’s a square all sides are 15 so u can add them up
The variable is the group that was given caffine, because thats what the doctors manipulated. They possibly altered the natural memory of the participants by giving them caffine. A more specific variable could be how much caffine each participant is given and what time are they given it.
Answer:
10.237 m/s²
Explanation:
The maximum acceleration will be at one end of the interval, or at a turning point in the interval. The turning points can be found where the derivative of acceleration is zero
A'(t) = 3t^2 -304t +12
The quadratic formula will tell the zeros of this.
t = (304±√(304^2 -4(3)(12)))/(2(3)) = (304 -√92272)/6 = (152 -√23068)/3
t ≈ 0.0394891
Then the maximum acceleration is ...
A(0.0394891) ≈ 10.23690 . . . . m/s^2

<em>Additional comment</em>
The maximum magnitude of acceleration is at t=6, where acceleration is ...
A(6) = -5174 . . . . m/s^2
This is more than 500 g's in the negative direction, so the race car is not expected to survive that long.

The attached graph shows the acceleration curve for positive acceleration. The acceleration continues to decrease to a minimum of -5174 m/s^2 at the right end of the interval [0, 6].
