Two balls are thrown horizontally. ball c is thrown with a force of 20 n, and ball d is thrown with a force of 40 n. assuming all other factors are equal, ball d will fall toward the ground

ball D will fall toward the ground at the same time as ball C

Explanation:

both balls experience the same downward (vertical) force of gravity as such they will both fall down at the same time, given that all other factors are equal.

although the ball were through with different forces,

those forces where in the horizontal direction but the force of gravity (downward force) will act on them equally to bring them down at the same time

an energy transformation flow diagram is shown

where is it ?

im guessing the west of station b
