Answer:
Explanation:
The time at which an object from from rest depends on air resistance, the height, gravity.
Since the question says we should neglect air resistance and both the ball and the bullet are from the same height they will get to the ground and the same time since they are both fired on earth which has the same gravity..
H=ut+1/2gt^2.
For an object dropping from a height the initial velocity is zero, therefore u=0m/s.
The formula becomes
t=√(2H/g)
So the time and object get to the ground depends on the height from the ground and gravity...
So since no air resistance they will get to the ground together.
