Answer:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
Given:
Formula:
where,
Solution:
[tex] \sf \: PE = m × g × h \\ \: \: \: \: \: \: \: \: \: \: \sf PE = 3.5 × 9.8 × 3.2 \\ \sf PE = \underline{ \boxed{ \orange{ \sf \: 109.76 \: J}}}[/tex]
Therefore, the potential energy of the rock is 109.76 joules.
