Why do you think it might be useful to know the distance between a gun fired and it's target?
inysia [295]
Distance plays an incredible factor, especially when taking into consideration especially long distances in terms of shooting a gun. You may be familiar with the Coriolis Effect, and how a bullet's trajectory will change in relation to the rotation of the Earth. The farther the distance, the greater the change in trajectory.

delivery ladies is Shivam noted at the thundering sound of 6 second after the lightning was seen by him​
vitfil [10]

Answer:

this is due to difference in speeds of sound and light

Explanation:

light has a speed of 3×10^8 m/s and it is seen at once because it takes negligible time due to very high speed and short distance  that is why as soon as lightning occurs we can see it . since thundering sound travels with speed of sound which is about 330  to 340 m/s in air hence it takes some time as described in question as 6 seconds

If you fired a rifle straight upwards at 1000 m/s, how far up will the bullet get?
nadya68 [22]

Answer:

h = 51020.40 meters

Explanation:

Speed of the rifle, v = 1000 m/s

Let h is the height gained by the bullet. It can be calculated using the conservation of energy as :

\dfrac{1}{2}mv^2=mgh

h=\dfrac{v^2}{2g}

h=\dfrac{(1000\ m/s)^2}{2\times 9.8\ m/s^2}                    

h = 51020.40 meters

So, the bullet will get up to a height of 51020.40 meters. Hence, this is the required solution.

Alenkinab [10]
To stop the car it would be 100m because if the car is going to 65km/h then it would still be 100km/h
