Physics help! A BB-gun is aimed directly at the center of a target 50m away. If the BB is fired horizontally at 350m/s how far below the bulls-eye wil the BB hit?

Question

anonymous · Answer

are you familiar with kinematic equations

anonymous · Answer

first find the time that the bullet takes to get to the target, this is in the x direction

we know V = d / t so, t =d / v

once we have time, we can put it into a kinematic equation to find the distance the bullet wil fall

use the equation d = 1/2*a*t^2

where d is the answer to the question, a is acceleratin due to gravity, and t is the time caculated in the first part.

Okay, I got .142 seconds for the time

anonymous · Answer

but I'm not sure if that's right because I plugged it in with that second equation and i got .0988036

anonymous · Answer

ok ill work it out and give you my answer

anonymous · Answer

I got pretty much the same, 0.1m, which is reasonable distance for the bullet to drop

anonymous · Answer

10cm seems about right

thank you so much for your help!
