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 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...

Forensic scientists can determine the speed at which a rifle fires a bullet by shooting into a heavy block hanging by a wire. As the bullet embeds itself in the block, the block and embedded bullet swing up; the impact speed is determined from the maximum angle of the swing (a) Which would make the block swing higher, a 0.204 Ruger bullet of mass 2.14 g and muzzle speed 1290 m/s or a 7-mm Remington Magnum bullet of mass 9.71...

1. Mountain roads often have switchbacks, a road weaving back and forth across the face of a mountain slope, so that on any portion of the road there is usually only a gentle incline. Why are these switchbacks used? Do switchbacks require less work for an automobile climbing the mountain than if the automobile went straight up a mountain slope? Does the answer depend on the frictional force on the car’s tires? 2. A 5.0 kilogram rifle fires a bullet...
