Physics: bullets, friction, and more?
It kinetic energy is KE = ½mV² KE = ½(.0078)(575)² = 1289 J since it penetrated to 0.055m, then the average work done to stop it, 1289 J, is FxD 1289 = 0.055 x F F = 234000 N (a) F = ma 234000 = 0.0078*a a = 3.01e7 m/s² t = √(2d/g) = √(2(0.055)/(3.01e7)) = 0.0000605 or 60µs .
Are there bullets that have GPS trackers in them?
In world war two they fired antiaircraft shells with vacuum tube proximity detectors inside, that detonated the shell when it was close to the enemy plane, So your idea is possibly workable for low velocity bullets and/or exploding bullets which could injure or kill even if they missed the target. The bullets could be made so the gps was not damaged unless the bullet hit a large bone in the victim. The antenna for the gps however will be difficult. Neil
How old do you have to be to buy .22 bullets?
I stand corrected, and I was terribly wrong. Please forgive me, I do apologize. I spoke too quickly and out of turn, as has been pointed out below. Mandatory minimum age is 18 for .22 bullets for a long rifle, and hand-gun ammunition mandatory minimum age is 21, be it for a .22 handgun or otherwise.
My bullet vibrator has stopped working, it is in the cord.?
Have u tried changing the batteries?
How long does it take a bullet wound to heal?
Holy cow...I seriously hope this is for research. The patients I have had in the hospital have taken a variety of recovery periods. You have to consider A LOT of factors like the age of the patient, their overall health after the GSW (rates of infection from an open wound), how healthy they were before the GSW (are they diabetic, a smoker, depressed), the path of the bullet (bones broken, tissue damaged, bones fragmented secondary to the GSW), how much they weigh, is the patient doing well at PT (phys therapy), are they getting out of bed when they can, are they eating well, peeing well,are their vitals stable? What about their psychological abilities as well. How are they coping with the GSW? Do they have support? Are they homeless? Are they a child? Has someone in their family ever been shot? All of these factors relate to their speed of recovery and when they will be discharged from the hospital. Also, what kind of insurance do they have? Some are forced out after only a few days. GENERALLY speaking...and I DO MEAN generally, for a healthy male ages 18-25: GSW to shoulder with shattered humerus and clavicle, healing time: Skin wound--3-6 months depending on the skill of the surgeon when repairing bone trauma from bullet bone healing--3-6 months Sling--3 months Discharge from hospital--10-14 days, barring no complications like blood loss, infection, satisfactory bloodwork,etc. GSW to lower extremity is GREATLY different. One patient I had--his femur was completely shattered and needed traction (oh...don't even go there. Not enough space to write about traction and weights) That patient ended up dying from a massive infection in the bone from infected pin sites. Alright, alright--uhhhh, say: Wound healing: 3-6 months barring any infection and skill of surgeon when repairing the bone and underlying tissues Discharge: 1-2 weeks Cane use: Possibly for life
How much damage would a .38 caliber revolver with hollow point bullets do to a human body or head?
Hollow points are meant to mushroom and flatten, having a larger surface area to do more tissue damage. at close range to the head it will be fatal and do a lot of damage. to the torso it would also cause significant damage, weather or not it would be fatal depends on the region , hit a vital organ ir liver heart you'd be in some ****, its a very popular cc ca, Even non hollow point 38s have a flat surface, so they have more surface area. it may penetrate and exit, but the most likely rout to penetrate and go straight through would be a 9mm or something like that with a high velocity.
