    Impulse Momentum
AI Thread Summary
The problem involves two average forces, F1 and F2, where F1 is three times larger than F2, and both forces produce the same impulse. The impulse-momentum theorem states that impulse equals force multiplied by time, leading to the equation F1t1 = F2t2. Given that F1 is three times F2, substituting this into the equation allows for solving the time interval for F2. The discussion emphasizes understanding the relationship between the forces and their respective time intervals to find the solution. Clarifying these relationships is crucial for completing the problem correctly.

Homework Statement



From Cutnell & Johnson PHYSICS 7th Edition Textbook - Ch 7 / Problem #1

One average force F1 has a magnitude that is three times as large as that of another average force F2. Both forces produce the same impulse. The average force F1 acts for a time interval of 3.2 ms. For what time interval does the average force F2 act?

Homework Equations



Note sure. I think...Impulse-Momentum Theorem

Ft = mvf - mvo

The Attempt at a Solution



No serious attempt made. I get tripped up in the wording of the problem. Any help would be appreciated.

Thanks!

The impulse is the product F*t as you say. If the impulses for the two forces are the same, we can say this with an equation. Use this to say that Impulse 1 is the same as Impulse 2 with an equation.
 
Thanks for the explanation, though truthfully I'm still not getting it...
 
Let's try this.

Impulse 1 = F1t1
Impulse 2 = F2t2

The problem says the impulses are equal. This means that

F1t1=F2t2

Can you finish from here? Don't forget to say with an equation that F1 is three times F2.
 
I'm inclined to write it as:

(3F1t1) = (F2t2)

Still thinking about the next step...
 
You replaced F1 with three times itself. Can F1 be the same as 3F1? What is F1 the same as? Re-read the question.

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}...
