Question

Find the gravitational potential energy of an object that has a mass of 12.0 kg and is is 4.8 m above the ground .​

Answer 1

Answer:

Given :-

• An object that has a mass of 12.0 kg and 4.8 m above the ground.

To Find :-

• What is the gravitational potential energy of an object.

Formula Used :-

$\clubsuit$ Gravitational Potential Energy Formula :

$\dashrightarrow \sf\boxed{\bold{\pink{P.E =\: mgh}}}$

where,

• P.E = Potential Energy
• m = Mass (kg)
• g = Acceleration due to gravity (m/s²)
• h = Height (m)

Solution :-

Given :

• Mass = 12.0 kg
• Acceleration due to gravity = 9.8 m/s²
• Height = 4.8 m

According to the question by using the formula we get,

$\implies \bf Potential\: Energy =\: mgh$

$\implies \sf Potential\: Energy =\: (12.0)(9.8)(4.8)$

$\implies \sf Potential\: Energy =\: 12.0 \times 9.8 \times 4.8$

$\implies \sf Potential\: Energy =\: 117.6 \times 4.8$

$\implies \sf\bold{\red{Potential\: Energy =\: 564.48\: J}}$

$\therefore$ The gravitational potential energy is 564.48 J .
