Momentum and Impulse 2. Your favorite rifle (22 caliber) has a mass of 3.0 kg, a 40 cm long barrel and weigh 2.6 g (a) Before you fire the rifle, how much momentum does the bullet have? (Not a trick question, I hope) (b) Before firing, what is the momentum of the rifle? (c) The bullet is fired with a velocity of 370 m/s. What is the bullet's momentum? (d) With what velocity does the rifle move backwards (Le. recoil)?...

9) A bullet with mass 0.0075 kg is fired with a gun with mass 0.95 kg. The bullet leaves the gun at 380 m/s. a) What is the recoil speed of the gun? Assume the gun was at rest before firing. b) Is the momentum of the bullet greater, smaller or equal (in magnitude) to the recoil momentum of the gun? c) Find both the kinetic energy of the bullet and of the gun. Which is bigger, or are they...

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...

A rifle with a mass of 78 kg fires a bullet with a mass of 36 g (0.036 kg). The bullet moves with a muzzle velocity of 4.6 m/s after the rifle is fired. (a) What is the momentum of the bullet after the rifle is fired? (b) If external forces acting on the rifle can be ignored, what is the recoil velocity of the rifle?

A bullet has a mass of 0.2 kg thrown by a rifle with a barrel length of 0.8 m. The force exercised in the bullet from the gases of the gun is F (x) = 100 + 100x - 200x ^ 2 Show that the work produced by gases in bullet, as it travels along the barrel, is equal to 3.0 kJ. Consider as a benchmark the position where the bullet starts to move, and that the travel of the...

A rifle has a 0.610 m long barrel. When fired, a bullet with a mass of 11.0 g accelerates from rest and exits the barrel at a speed of 850 m/s. What is the net force on the bullet (in N) while it is in the barrel? ( Enter the magnitude. Assume a constant acceleration)

7. X You decide to try out your new rifle on a test range. The manufacturer says that a mo=4 g bullet is fired initially at a velocity of Voi=400 m/s. You decide to use this information to find the coefficient of friction between a block of wood and a concrete patio on which the block, m=0.8 kg, rests. The bullet, when fired, passes entirely through the block and emerges from the other side at 120 m/s. The block of...
