Answer:
It can be calculated from Snell's law by setting the refraction angle i.e. equal to 90°.
Hope it helps!
I'm such a devoted NASCAR fan that I don't even know if the starting line and finish line at Indy are the same line ... or maybe they're in different places, like the 100-meter sprint in track.
I have no idea, but I'm going to guess that the start and finish at Indy are the SAME line.
If that's true, then the displacement of a car that runs the whole 500 miles is very close to <em>ZERO</em>.
Displacement is the distance and direction between the place where the object starts out and the place where it ends up. The route it follows to get from the start to the finish is completely ignored, and doesn't matter.

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.
