Question

Red ball is thrown horizontally at 5 m/s. simultaneously, a green ball is dropped from the same height. Assuming the floor is flat and air resistance is negligible, which ball will hit the ground first? A. The red ball B. the green ball C. Both will hit the ground at the same time D. Whichever ball is heavier will hit the ground first Red ball is thrown horizontally at 5 m/s. simultaneously, a green ball is dropped from the same height.

Explanation / Answer

C) Both will hit the ground at the same time as their vertical initial velocity is same(i.e. here Vo = 0) though at different location on ground. Vertical motion will be same if their initial vertical components are same irrsepective of their horizontal motion. Time of flight only depends on vertical variables.
