Question
A ball 
is dropped vertically and another ball 
is thrown horizontally with the same velocities from the same height and at the same time. If air resistance is neglected, then
- Ball reaches the ground first
- Ball reaches the ground first
- Both reach the ground at the same time
- The respective masses of the two balls will decide the time
reaches the ground first reaches the ground first The correct answer is: Both reach the ground at the same time
Vertical component of velocities of both the balls are same and equal to zero. So
