Re: At what angle will a bullet ricochet off water?

As you have learned empirically, angle and velocity are important factors in ricochet, but there are many others; mineral content of the water, temperature, shape of the projectile, rate of spin of the projectile, hardness of the bullet, any deformations or imperfections on the surface of the bullet, etc.

A block struck by a bullet — Collection of Solved Problems

A wooden block with mass M = 3 kg is lying on a horizontal table. It is hit by a bullet with mass m = 5 g which moves horizontally. The bullet remains in the block after colliding with it. The block moves on the table a distance d = 25 cm. The coefficient of kinetic friction μ k = 0.2. Find the starting speed of the bullet.

Q & A: Shooting and dropping bullets - Department of Physics

The question of a fired vs a falling bullet is an interesting thought experiment. It would seem to me that a bullet fired with significant velocity at a perfectly horizontal angle to the immediate plane of the earth (in other words perfectly perpendicular to the earth's gravitational force) would hit the ground after the other bullet, being of identical size and mass, which is dropped from the ...

Mathematical Model for Bullet Ricochet

bullet. If EL is the loss of energy due to ricochet, EL = Ex - ER = E 1 - a 2 Cos2 i - 2 Sin2 i]. (12) Impulsive force during ricochet: The impact of a bullet on a target is in the form of an impulse, i.e. a large force acting for a very short time. The value of the average force acting on the bullet can be de-

The trick with this kind of physics problem is to view the earth from the vantage point of an external observer who is say, fixed in position relative to the distant stars, and so sees the earth as a spinning sphere and sees the point at which the bullet is fired as …

Speed of a Bullet - The Physics Factbook

The velocity of a bullet is given in feet per second (fps) in the United States. The 0.22 rimfire cartridge, which has a very small powder charge, sends its bullets on their way at between 370 m/s and 460 m/s. Cartridges in rifles -- centerfire cartridges -- propel their bullets at a much faster rate. The 0.220 Swift, which drives a very small ...

Fluid simulation on Bullet Physics - Math and Physics ...

EDIT: Actually, I forgot to say I'm focusing on water (and maybe fire/smoke). So "Particle based viscoelastic fluids" isn't the best option because. Our method is specifically designed for fast simulation of rapidly moving fluids, but is not as well adapted for simulation of low viscosity liquids such as water.

Can Being Underwater Protect You From Bullets? » Science ABC

A TV show has tested this in reality! Mythbusters, a popular Discovery Channel program, tested the "bullet-proof" ability of water in one of its episodes.After shooting into the water with a variety of rifles, including a 9mm pistol, shotgun, M1 Garand semi-automatic supersonic rifle, and a 50-caliber rifle, they concluded that you could protect yourself from an underwater onslaught of ...

Q & A: bullets dropped and fired | Department of Physics ...

If the bullet during its flight points its axis not quite along its axis of travel, the lift could point up or down. Of course the average expected value of the lift is zero if the system is symmetric, but even a tiny random flaw in the bullet can cause some nonzero lift, and if there's a crosswind, the Magnus effect may be not very small either.

How far can a bullet travel underwater if fired from above ...

Answer (1 of 13): It depends. A large fat but slow pistol caliber bullet can travel farther. A fast long pointed rifle caliber bullet can in some cases shatter as it turns sideways, depending on bullet construction and speed > MythBusters Episode 34: Bulletproof Water Premier Date: July 13, 2...

projectile - Why does a bullet bounce off water? - Physics ...

Imagine a bullet bouncing off another bullet, or metal armour. No problem accepting that, it's just Newton's laws and momentum. well water also has mass and needs a force to accelerate it in exactly the same way - the only difference in bouncing a bullet, or a stone, or a bomb, is the speed and angle and how much water you need to move and how ...

Projectile Motion | Physics

Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory.The motion of falling objects, as covered in Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement.

At what angle will a bullet ricochet off water?

Area of science: Physics ID: 1112580718.Ph. Message: I hunt turtles with a rifle. If a fire a bullet at the turtle at a shallow angle and miss, the bullet will bounce off the water, creating a dangerous condition for any bystanders.

Ricochet Analysis Introduction - Ballistics - Bev Fitchett ...

Ricochet Analysis Introduction. When a bullet strikes any surface, there is a critical angle at which the bullet will bounce off or ricochet from the surface rather than penetrate. After ricocheting from the surface, the missile will lose a considerable amount of its velocity (anything up to 35% in test firings) and, invariably, lose its stability.

Water speed and bullet penetration | Physics Forums

73. 6. I think that the speed of water would effect the bullet too. Because if the water is stand still and the bullet move the water is move too (from the bullet view). So if the water is move so it speed would increase or reduce (from the bullet view) make the friction would increase or reduce make the bullet speed increase or reduce.
