Question 548552
An object is thrown straight up into the air. The table below shows the height of the object as it ascends.
Time (s)--- 0----0.1----0.2----0.3----0.4----0.5----0.6
Height(m) 0---- 1 ----1.8----2.6----3.2----3.8----4.2
A) Perform a non-linear regression for these data. Record the equation of best fit and the coefficient of determination.
y = -5.2381x^2 + 10.1429x + 0.0095; R = sqrt(0.9997)
----------------------------------------------------

B) Use your model to predict the maximum height of the object and how long the object will be in the air?
Ans: 4.9196
----------------------------------------------------

C) Do you think the model is accurate?
I'll leave that to you.
