A. 314 because when you use the formula for the GPE ; GPE=MGH or means mass times gravity time height (4x8x9.8) and thats equivalent to 313.6 which rounds up to 314. Hope it helps 

Answer:

The gravitational potential energy is 314 J.

(A) is correct option.

Explanation:  

Given that,

Mass of dog = 4 kg

Height = 8 m

We need to calculate the potential energy

Using formula of potential energy

[tex]P.E = mgh[/tex]

m = mass

g = acceleration due to gravity

h = height

Put the value into the formula

[tex]P.E=4\times9.8\times8[/tex]

[tex]P.E=313.6=314\ J[/tex]

Hence, The gravitational potential energy is 314 J.
