Well, since you assumed continuity of the system, then you can said, mdot1 equals to mdot2 and solve the equation without looking for V in, unless it's demanded in the problem.

Brian, you're a great teacher! Bless you

I was hoping to make it through the rest of the problem, and actually solve for the answer! I pray that you can answer my question I have for the very last step: How would I enter the velocity vector in the Fbolt equation? would I just treat it as a magnitude and square the velocities in the final step?

Amazing video thank you

How did you know to choose B=mv?

[@yashkona7960]

where is the answer bro

How do you know the direction of the force on the bolt before solving? I got Fbolts as -7408.76 N. Also, since there are 2 bolts, how do you account for that? Divide or multiply by 2?
