A fire arm of mass 0.1 kg fires a bullet of mass 1g that gains a velocity of 10 m/sec. The velocity gain of the fire arm due to recoil is 0.1m/sec. By how much foes the momentum of the fire arm increase, measured in kg m/sec?
Homework Answers
Solution:
initial momentum of fire arm = 0 kgm/s
final momentum of fire arm = m * v = 0.1 * 0.1 = 0.01 kgm/s
=> increase in momentum = 0.01 - 0
=> increase in momentum = 0.01 kg m/s

A Styer AMR (Anti-Materiel Rifle) with a mass of 18 kg fires a fires a 20 gram bullet to have a muzzle velocity of 1450 m/s. The average time it takes to reach that muzzle velocity is 0.004 seconds. Since you are holding the gun to keep it horizontal and pushing back on the recoil to keep the AMR stationary.. a) Draw an appropriate momentum diagram for this process... b) And determine the average force you apply to the Styer...

A gun with inertia 5.5 kg fires a 13-g bullet at a stationary target located 1.0 km away. After the bullet leaves the gun, its speed decreases (constant x component of acceleration a = -1.0 m/s2 ) so that the bullet hits the target at 299 m/s. If the direction in which the bullet moves is along a positive x coordinate axis, what is the recoil velocity of the gun?

In principle, when you fire a rifle, the recoil should push you backward. How big a push will it give? Let's find out by doing a calculation in a very artificial situation. Suppose a man standing on frictionless ice fires a rifle horizontally. The mass of the man together with the rifle is 70 kg, and the mass of the bullet is 10 g. If the bullet leaves the muzzle at a speed of 500 m/s, what is the final...
