Question

A golf ball is dropped out of an airplane. The downward velocity of the ball at various times is given in the table below. What is the slope of the line that fits this data?

Answer 1

Let:

`\begin{gathered} (x1,y1)=(1,21.8) \\ (x2,y2)=(2.2,33.56) \\ \text{Slope}=m=(y2-y1)/(x2-x1)=(33.56-21.8)/(2.2-1)=(11.76)/(1.2)=9.8 \end{gathered}`
