How do you conclude the answer to the following : What will be the approximate pressure (bar/psi ) for a bullet shaped object weighing 35kg..500mm diameter x 900mm. to travel horizontally for a distance of 30 metres before landing..

Answer 1

What pressure, where? The ambient pressure can be anything.

No object will travel perfectly horizontal. It will follow a parabolic path.

bar/psi is not a unit of pressure. It is two units, written weirdly.
1 bar = 14.7 psi

If this is an assigned homework question, you must have copied part of it incorrectly.

Answer 2

Right are you sat down ? Well this object nearly killed a work collegue of mine..the company involved are not remotely concerned, even though this projectile came out of the safety zone by 20 metres. Now as the projectile was approximately no more than 2 metres off the ground, the ambient pressure around it and us is 1 bar..yet to keep it all simple we are trying to understand the force or pressure and maybe the speed in order to highlight the dangerous situation they had created and inform them of the regulations which have been breached by showing this projectile answer.. Thankyou in advance
