Question

A man shoots a rifle at a height of 1.7 m above level ground. His aim is perfectly horizontal. At the same time the bullet leaves the barrel of the gun at 670 m/s, the shell casing is ejected with a velocity of 3 m/s, also perfectly horizontal to the ground (but at an angle of 90° to the path of the bullet.)

Answer 1

Is there a question here?

Answer 2

I predict that the shell lands closer to the shooter than does the bullet!

Oh, did you want to ask a question, too?

Something tells me you will need to find out how long it takes an object to fall 1.7 meters.

Answer 3

I bet they both hit the ground at the same time, whenever that is.
