    paper helicopter model

    ok so i got did the helicopter test several times, where you cut rotor and drop froma height then repeat over and over again


    it says "develop a model" use your data to produce a model to predict the time it takes for the paper helicopter to drop to the floor (y) based on rotor length (x)

    I think it means regression model? am i right ?
    Anyways I did each regression model and got quartic which has r2=0.97 closer to r2 =1 than all the other regression models.

    it says use the equation of your model to answer questions: I got a long formula in my calculator and im guessing i have to sub in numbers to get answers :0! am i going on the right track?
