Question

Qual o valor da energia potencial gravitacional de uma pessoa de 80 kg de massa no topo de uma montanha de 30 m de altura? (Adote g= 10 m/s2)

Answer 1

$\mathsf{E_{pg} = mgh}$

$\mathsf{E_{pg} = 80 \times 10 \times 30}$

$\mathsf{E_{pg} = 800 \times 30}$

$\boxed{\boxed{\mathsf{E_{pg} = 2400J}}}$

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \hookrightarrow\boxed{ \boxed{ { \bf{ E_{Pg} = 24000~J }}}} \end{gathered} }$

• Explicação:

$\Large\displaystyle\text{ \begin{gathered} \sf{ E_{Pg} = m \cdot g \cdot h } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{ E_{Pg} = 80\cdot10 \cdot30} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{ \boxed{\sf{ E_{Pg} = 24000\:J }} } \end{gathered} }$
