Transcript text: Calculating Conservation of Energy
A 6.1 kg brick falls from a roof. At $3.0 \mathrm{~s}, \mathrm{t}$ brick reaches the ground at 0 m .
What is the potential energy of the brick?
\[
\begin{array}{c}
E_{p}=[?] \mathrm{J} \\
E_{p}=m g h
\end{array}
\]
For gravitational acceleration, use $g=10 \mathrm{~m} / \mathrm{s}^{2}$.
0 J
300 J
