Hey guys,
I confused about something,please help me.
I have a bullet and its diameter is 0.5 inches. its speed is 400 foot /sec.
It makes one complete rotation in the gun 120 mm per turn and length of the gun is 1.5 meter.
How can I calculate the rotational and angular speed?
-I used a formula for rotational speed;
R=2pi.n n=(number of the rotation) which is 1.5 meter/1.2 mm.
- Angular speed;
w=v/r w=400 ftsec/0.5inch
Are my formulas and calculations correct?
