Question

what is the energy required to lift an object of mass 25 kg to a height of 10 m ?

Answer 1

$\fbox{ \fbox{ \large{\bold{Given :- \: }}}}$

$\to \bold{Mass \: ( M )= 25 \: Kg \: } \\ \to \bold{Height \: ( H ) = 10 \: Meter \: } \\ \to \bold{Acceleration \: Due \: To \: Gravity \: ( g ) = 9.81 \: m {s}^{ - 2} \: }$

$\large{ \bold{ \fbox{ \fbox{To \: Find :- \: }}}}$

$\to \bold{Potential \: Energy = \: \bold{? }\: }$

$\large{\bold{ \fbox{ \fbox{Solution :- \: }}}}$

$\large{ \bold{ \underline{ \: We \: Know \: That \: , \: \: }}}$

$\bold{ \huge{ \fbox{Potential \: Energy \: = \: MgH \: }}}$

$\to \bold{Potential \: Energy = 25 \: × \: 10 \: × \: 9.81 } \\ \to \bold{Potential \: Energy = 2452.5 \: Joules \: }$

Answer 2

$\huge \red { \boxed{ \boxed{ \mathsf{ \mid \ulcorner Answer : \urcorner \mid }}}}$

Mass (m) = 25 kg

Height = 10 m

Gravitational Force (g) = 9.8 m/s²

===============================

We have formula :-

$\huge{\boxed{\boxed{\sf{P.E \: = \: mgh}}}}$

________________[Put Values]

P.E = (25)(10)(9.8)

P.E = 2450

$\huge{\boxed{\boxed{\sf{P.E \: = \: 2450 \: J}}}}$
