If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away

If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away

The muzzle velocity of the bullet is 275 m/s

y = -1.1109 m

Explanation:

Range =

range = 85 m

velocity = 275 m/s

g = 9.8 m/s²

If the bullet is aimed at a target 180 m, time required to travel 180 m with horizontal component will be;

t = 0.6546 sec

To determine, how low as a positive number in meters.

y =

y = 0.9909 - 2.1018

y = -1.1109 m

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
