Question

Calculate the potential energy of a 5.2 kg object positioned 5.8 m above the ground.

Answer 1

Answer:

295.568J

Explanation:

use P=mgh

plug in givens

P= 5.2*9.8*5.8= 295.568J

Answer 2

$\bf \huge \hookrightarrow \:Given :$

$\bf \implies \: Weight \: \: of \: \: Object \: = 5.2 \: kg$

$\bf \implies \: Height \: = 5.8m$

_________________________

$\bf \huge \hookrightarrow \:To \: \: Find$

☛ Potential Energy of object.

_________________________

$\bf \Large \hookrightarrow \:Formula \: \: using$

$\Large \mid \underline {\bf {{{\color{orange}{p \: = \: mgh}}}}} \mid$

• P denotes Potential Energy

• m denotes mass

• g denotes gravitational field

• h denotes height

_________________________

☛ Now , putting the values in formula.

• We know that , the gravitational field of earth is 9.8.

$\bf \Large \mapsto \: \: 5.2 \: \times 9.8 \: \times 5.8 \\ \\ \bf \Large \mapsto \: \: 50.96 \: \times 5.8 \\ \\ \bf \Large \mapsto \: \: 295.56$
