AI Thread Summary
To calculate the average recoil force during an 8-shot burst from an assault weapon, one must consider the conservation of momentum. The burst rate of 1000 rounds per minute indicates that each shot is fired in 0.008 seconds. The mass of each bullet is 7.49 grams, and its speed is 299 m/s. Understanding the relationship between the burst duration and the firing rate is crucial for determining the recoil force. The discussion emphasizes the importance of these concepts in solving the problem effectively.

Homework Statement


A soldier on a firing range fires an 8-shot burst from an assault weapon at a full automatic rate of 1000 rounds per minute. Each bullet has a mass of 7.49 g and a speed of 299 m/s relative to the ground as it leaves the barrel of the weapon.

i don't understand how 8-shot burst and 1000rounds are related
i don't know how to start this question and what basic concept should be used

Hi zhuyilun! :smile:

When a bullet leaves a gun, the gun recoils, which means that it moves backwards.

It does so because of conservation of momentum. :wink:

(and what is the relationship between force and momentum?)

i get this part now~! thanks, but what is the relationship between 8-shot burst and 1000 rounds per second

It's telling you that the burst takes .008 seconds. :smile:
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
