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

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 :

Where,

m is the mass of the object

g is acceleration due to gravity

h is the height of the object from the ground.

Hence, this is the required solution.

it about 600 mph from what i calculated

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
