In the figure above, which of the following is the pathway of light that allows

Light bulb -> child’s eyes -> ball

Explanation:

I don’t know if it’s correct but I think that’s the answer

1250 m

Explanation:

This situation is related to vertical movement and can be modelled by the following equation:

Where:

is the height of the alien spaceship at a given time

is the initial height of the alien spaceship (we are told it was already 500 m above the ground)

is the initial velocity of the alien spaceship, that is also constant. This means the velocity is the same during the whole motion and there is no acceleration.

is the time

is the acceleration

Rewritting the equation with the given conditions:
