A 2.5 kg falcon soaring at a height of 500 meters has a certain potential energy. Now suppose the falcon were carrying a 1.0 kg snake. What would the new height be if the total potential energy were to remain the same?

Respuesta :

Answer:

The new height is 357.143m

Explanation:

Given:

Mass of the falcon (M) = 2.5 kg

Height of the falcon (H) = 500 m

Mass of the snake (m) = 1 kg

To Find:

Thew new Height if the total potential energy were to remain the same = ?

Solution:

Now,the initial potential energy would be given by

[tex]P_1 = MgH[/tex]

And the final potential energy would be  

[tex]P_2 = (M+m)gh[/tex]

where

h is the new height

Now, the potential energy is same

Therefore,

[tex]P_1 =P_2[/tex]

[tex]MgH = (M+m)gh[/tex]

[tex]MH = (M+m)h[/tex]

On Substituting the values,

[tex]2.5\times 500 =(1+2.5) \times h[/tex]

[tex]1250 = (3.5 )h[/tex]

[tex]h = \frac{1250}{3.5}[/tex]

h =357.143 m
