Question

On top of a 3 m tall shelf sits a lonely 45 kg toy snake. How much gravitational potential energy (GPE) does this snake have on Earth2 where g = 9.3 m/s^2?

a) 130.5 J
b) 139.5 J
c) 139.7 J
d) 137.7 J

Answer 1

To find the gravitational potential energy of the toy snake on Earth2, use the formula GPE = m × g × h. Using the values provided, it calculates to 1252.5 J, which does not match any of the options, suggesting an error in the question.

Step-by-step explanation:

To calculate the gravitational potential energy (GPE) of the toy snake on Earth2, we use the formula GPE = m × g × h, where m is the mass of the object, g is the acceleration due to gravity, and h is the height above the ground.

In this case, the mass of the toy snake (m) is 45 kg, the acceleration due to gravity on Earth2 (g) is 9.3 m/s², and the height of the shelf (h) is 3 m. Plugging these values into the formula gives us:

GPE = 45 kg × 9.3 m/s² × 3 m = 1252.5 J.

However, none of the options match this result, indicating there may have been a typo or error in the question or the options provided.
