how high is a 0.1 kilogram bird from the ground when its potential energy is 3 joules?

how high is a 01 kilogram bird from the ground when its potential energy is 3 joules class=

Respuesta :

mass = 0,1 kg
energy = 3 J

U = m.g.h
3 = 0,1.10.h
3 = 1h

h = 3 meters high

Answer : Height of the object from the ground is, h = 3.06 m.

Explanation :

It is given that,

Mass of the bird, m = 0.1 kg

Potential energy, PE = 3 J

We know that mathematically the potential energy of an object is given as :

[tex]PE=mgh[/tex]

Where,

m is the mass of the object

g is acceleration due to gravity

h is the height of the object from the ground.

[tex]h=\dfrac{PE}{mg}[/tex]

[tex]h=\dfrac{3\ J}{0.1\ kg\times 9.8\ m/s^2}[/tex]

[tex]h=3.06\ m[/tex]

Hence, this is the required solution.
