If a gun is sighted to hit targets that are at the same height as the gun and 95 m away, how low will the bullet hit if aimed directly at a target 195 m away? the muzzle velocity of the bullet is 275 m/s.

Horizontal distance between the bullet and the target (s) = 195 m

Horizontal velocity of the bullet (u) = 275 m/s

Time taken to cover the horizontal distance =

Time taken (t) =

t = 0.709 s

Now, in the vertical direction:

Initial velocity (u) = 0 m/s

Let the depth covered be h.

Time taken (T) = 0.709 s

Acceleration due to gravity (g) = 9.8 m/s^2

Now, using the seconds equation of motion:

h = 2.463 meters

Hence, the bullet will hit 2.463 meters below the target.

true tan speed = ang vel x radius

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
