Question 1

28812

A stone is thrown from a height of 9 m above the ground. From the graph determine the average velocity in the first second.

Answer

\(\text{3 m/s}\)

Worked Solution

\begin{align}
&x(1)=12 \\
&x(0)=9 \\
&\begin{aligned}
\text { Average velocity } &=\frac{x(1)-x(0)}{1-0} \\
&=\frac{12-9}{1} \\
&=3 \mathrm{~m} / \mathrm{s}
\end{aligned}
\end{align}
