What hits the ground first?? 1. The problem statement, all variables and given/known data If we simultaneously throw two tennis balls horizontally from the top of a building, one at 10 m/s and the other at 14 m/s. Neglecting the air resistance, which one will hit the ground first??? 2. Relevant equations i dont think we use equations, but we have to consider the speed of each ball and how they are thrown horizontally?? 3. The attempt at a solution I think the ball with 10 m/s should hit the ground first because it wont reach far and eventually fall vertically from the top of buliding ?? please help out??
