✏️ Potential Energy

${\Large{\overline{\underline{\bold{✎ \:Answer:}}}}}$

The potential energy of the object is 980 J.

Solution:

Given:

the mass of the object $\sf m$ = 50 kg
the object's height above the reference point (ground) $\sf h$ = 2 m

Solve using the formula for calculating potential energy. Note that g = 9.8 m/s².

${\large{\boxed{\sf{P.E. = m \: \times \: g \: \times \: h}}}}$

$\sf{P.E. = (50\:kg) \times (9.8 \: \frac{m}{s^2}) \times (2\:m)}$
$\sf{P.E. = (490\:N) \times (2\:m)}$
${\sf \therefore P.E. = {\boxed{\green{\sf{980\:J}}}}}$
