At the instant that you fire a bullet horizontally from a rifle, you drop a bullet from the height of the gun barrel. If there is no air resistance, which bullet hits the level ground first? Explain.
Solution 5DQ Step 1 : In this question, we have two bullets fired at same instant One bullet is fired horizontally from the rifle Another bullet is dropped from the height of gun barrel We need explain which bullet hits the ground first, ignoring the air resistance Step 2 : When a bullet is fired horizontally and dropped vertically , both are acted upon by the gravitational forces, which is constant for any object Since we are ignoring the air resistance, we will have have only gravitational force acting upon the bullets Hence both the bullets hit the ground at same instant
