Respuesta :

The gravitational potential energy gained by the Koala is 2234 J

Solution:

Gravitational potential energy (GPE) is given by:

[tex]GPE = m \times g \times h[/tex]

Where,

m is the mass

h is height

g is acceleration due to gravity

[tex]g = 9.8 m/s^2[/tex]

From given,

m = 12 kg

h = 19 m

Substituting we get,

[tex]GPE = 12 \times 9.8 \times 19\\\\GPE = 2234.4\\\\GPE \approx 2234[/tex]

Thus the gravitational potential energy gained by the Koala is 2234 J
