A marksman at rest fires a 4.00-kg gun that expels a bullet of mass 0.0140 kg with a velocity of 181 m/s. The marksman's mass is 81.0 kg. What is the marksman's velocity after firing the gun? mc = 85kg md = 0.0140 -(0.0140)(-181)/85 = .0298 m/s

The largest railway gun ever built was called Gustav and was used briefly in World War II. The gun, mount, and train car had a total mass of 1.22 106 kg. The gun fired a projectile that was 80.0 cm in diameter and weighed 7502 kg. In the firing illustrated in the figure, the ...

Assuming the gun/bullet combo was initially at rest, conserve momentum to get (.21)(v) + (5.6)(-2.5) = 0 I think that's a heavy, slow bullet!

From the top of a tall building, a gun is fired. The bullet leaves the gun at a speed of 340 m/s, parallel to the ground. The bullet puts a hole in a window of another building and hits the wall that faces the window. (y = 0.42 m, and x = 7.2 m.)Determine the distances D and H...

A 8.3-g bullet, when fired from a gun into a 1.1-kg block of wood held in a vise, penetrates the block to a depth of 7.05cm. This block of wood is next placed on a frictionless horizontal surface, and a second 8.3-g bullet is fired from the gun into the block. To what depth (...

A bullet of mass 0.0019 kg moving at 487 m/s embeds itself in a large fixed piece of wood and travels 0.55 m before coming to rest. Assume that the deceleration of the bullet is constant. What force is exerted by the wood on the bullet?

When you think about the conservation of momentum, there is always some force going in both directions. The mass and velocity of the water coming out of the fire-fighter's hose makes the tube want to move backwards, because there is a force pushing the hose in the opposite ...

Three guns are aimed at the center of a circle,and each fires a bullet simultaneously. The directions in which they fire are 120 degrees apart. Two of the bullets have the same mass of 4.50*10^-3 kg and the same speed of 324 m/s. The other bullet has an unknown mass and a ...

a toy spring gun is used to shoot 28-g bullets vertically upward. the un deformed length is 150 mm, it is compressed to a length of 25 mm when the gun is ready to be shoot and expands to a length of 75mm as the bullet leaves the gun. a force of 45 N is required to maintain the...

A Few questions- please help!!! also show steps! What magnitude of force, acting for 0.025 s, will change the velocity of a 100 g ball from 30 m/s eastward to 40 m/s westward? A girl holds a 1.7 kg air rifle loosely and fires a bullet of mass 2 g. The muzzle velocity of the ...
