Answer:
We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.
The excel output is attached here.
Therefore, the equation of the linear regression is:
Where:
21.9028 is the intercept and 1.5736 is the slope.
Answer:
t = 1.143 s
Step-by-step explanation:
The equation he uses to model the height of the rocket in cm, as function of time is
h(t) = -490 t^2 + 1120t
We can plot this equation using a graphing tool
Please, see attached picture
The rocket reaches his maximum height (640 cm) at
t = 1.143 s
