# What is the kinetic energy of a baseball traveling 90 mph?

A baseball weighs 145 grams 90 mph = 40.23 meters/sec KE = 1/2 mass x v2 = .5 x 145g x (40.23m/s)2 = 72.5g x 1618.45 m2/s2 = 117337.84 g m2/s2 = 117.34 kg m2/s2 = 117.34 J…oules

# How far does a bullet travel from a rifle?

Depends on the caliber of the rifle and the elevation of the barrel above the horizontal. A .22 LR fired at about a 30 degree angle can travel about 1.5 miles. A 30-06 about 4….5 miles.

# How fast does a bullet travel in mph?

761 mph (miles per hour) (The muzzle velocity of a bullet varies widely depending on the caliber, type of bullet, type of cartridge, the powder charge, and the gun barrel. Muz…zle velocities range from large caliber pistols as slow as 245 m/s, to high-powered rifles as fast as 1200 m/s, to tank rounds as fast as 1800 m/s. More .22 Long Rifle rounds have been produced than any other round.) Small short barreled pistols have low velocities around 340 mph. Long barreled rifles have velocities of 3,400 MPH Experimental rail guns have shot bullets at 7,602 MPH

# How many mph does a bullet travel?

It depends on several factors. Bullet can travel as slow as a few hundred feet per second up to several thousand feet per second. 1000 feet per second is about 682 MPH.

# How high can a rifle bullet travel straight up?

Depends on the rifle and the cartridge that it fires. A 30-06 firing a 180 grain bullet can reach just over 10,000 ft straight up. Data taken from Gen. Julian Hatcher's ballis…tic research for the US Army.

# How is foot pounds of energy measured for bullet impact?

It can be projected by using the formula E= MV 2 divided by 450400. E is the energy in foot lbs M is mass of bullet in grains V 2 is velocity in feet per second, squared. …It can also be directly measured by taking a known weight, shooting it, and measuring the movement of the weight. This is known as a ballistic pendulum, and is not often used today.

# How does the accerelation of the rifle compare with that of the bullet?

When a bullet is fired out of a gun, the bullet's acceleration and the gun's acceleration are equal in magnitude by opposite in direction. This is the cause of kickback from t…he gun. The reason why the gun doesn't rip your arm off though is because it's sheer size or mass, resulting in a much smaller impact on the object it collides with.

# How does kinetic energy affect the stopping distance of a vehicle travelling at 30 mph compare to the same vehicle travelling at 60 mph?

Kinetic energy equals one half times mass times velocity squared. If the velocity is doubled, from 30MPH to 60 MPH, the kinetic energy for the same mass would be four times gr…eater.
