Kinetic energy of the Monster Hunter cannon

AI Thread Summary
To calculate the kinetic energy of the gunpowder cannon in Monster Hunter, the formula KE=½mv² is used, where m is the mass of the projectile and v is its velocity. The kinetic energy can be measured at the muzzle or the target, with the latter being lower due to air resistance. An example provided shows that a 1000 kg projectile launched at 1000 m/s has a kinetic energy of 0.5 GJ. Participants are encouraged to demonstrate their understanding and effort in approaching the calculation. The discussion emphasizes the importance of following homework guidelines for clarity and structure.

I do not think this is actually a homework question. Can you provide more detail on what you want?

The generic formula is KE=½mv2, where m is the projectile mass and v is the velocity. You can take the values at the muzzel or at the target. The KE at the target is less due to air resistance.

A 1000 kg projectile launched at 1000m/s has KE=0.5GJ. For a real world example, look at

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}...

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
