Question
Q2. A spring loaded gun is aimed horizontally and is used to launch identical balls with different initial speeds. The gun is at the fixed position above the floor. The balls are fired one at a time. If the speed of the second ball fired is twice the speed of the first ball fired, how is the horizontal range affected? Neglect air-friction.The range of the second ball will be twice as large as that of the first ball.
The range of the second ball will be smaller than that of the first ball by a factor 1.4.
The range of the second ball will be half as much as that of the first ball.
The range of the second ball is about 1.4 times larger than that of the first ball.
The range for both balls will be the same.
Explanation / Answer
The gun is aimed horizontally so no effect on vertical velocity.
So there is no effect on time of projectile.
If speed of second ball is double
than
The range of the second ball will be twice as large as that of the first ball.
