Abrick falls from 12 m scaffolding. what is the final velocity of the brick if it was initially at rest? how much time passes during the fall?

Final velocity is 39.2 m/s and it travels 78.4 m/s

Explanation:

I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance. Hope this helps.
