In which of the following cases does a ball which is thrown or released from the top of a building have the least speed at impact? Assume that the building is in the middle of a flat plain, and that air resistance is negligible, and that all throws produce a speed of 25.0 m/s initially. Group of answer choices The ball is thrown straight up in the air The ball is thrown straight down The ball is thrown straight forward The ball is simply dropped (released with no initial speed) The ball is thrown forward and up (diagonally) The ball is thrown forward and down (diagonally) All of the above are equal
