Compare the acceleration that you found by your velocity function, to the acceleration of the function of the object that I found by taking the derivative.
v(t) = 0.9t – 2
Then through an xy scatter, I got this equation for the velocity:
v(t) = 0.6 - 4t + 5t2 -2t3 + 0.2t4
Then I found the acceleration function by taking this derivative.
How do I compare the acceleration of the line regression: 0.9m/s2 to the function I found by taking the derivative?
