If I shoot a bullet horizontally at a target and I miss by 3 cm, can I calculate the speed of the bullet?

How do you apply ballistic coefficient for bullets that have a longer time of flight where drag comes into play. Furthermore drag changes as the bullet slows.

1-at the instant a gun fires a bullet horizontally, an identical bullet is dropped from rest vertically to the ground. which one hits the ground first? explain 2- what would be the trajectory of a projectile if gravity were zero?

@grantwaldeck7009 6 жыл бұрын

1 they would both hit the ground at the same time. because in projectile motion x and Y are disconnected from each other. And in your scenario the only downward force is gravity. therefore because gravity acts on everything the same way, they would land at the same exact time 2 If gravity were zero then the bullet would carry on endlessly until air resistance stopped it

zero is a constinant? or is zero a infinite?

how is the xi zero ? shouldnt it be 50 ? since it was 50 meters far from the target ? or is it because our reference point is the man ? so we took the xi zero ?

To calculate Time Of flight of your givens, wouldn't you just take the rate of gravity being 9.81m/s and bullet drop being .03m .03/9.81 ToF = .003 sec ?? And so on for MV? What's all the other jargon for?
