Calculate Travel Time for Plane with Ground Velocity of 796km/h in 100km [N]

AI Thread Summary
To calculate the travel time for a plane flying 100 km north with a ground velocity of 796 km/h at 25 degrees west of north, the vertical component of the velocity must be determined. This involves using the formula for the northward component, which is 796 * cos(25). The time can then be calculated using the formula T = D/V, where D is 100 km and V is the northward velocity. The discussion highlights the importance of understanding vector components in solving the problem. Accurate calculations will yield the required travel time for the flight.

1. How long will it take a plane to travel 100km [N] if its ground velocity is 796km/h [25 W of N]

I am having the hardest time with question since I actually don't know how to start. I know it require the fomula T= V*D. I manage to get a diagram but that is far as I gone. =(

Help? I have a final tomorrow and I need to able to do this kind of questions.

It is an odd question. Are you sure you weren't given any information about the wind speed and direction?

As it stands, I would say you are just asked to find the vertical or north component of the vector. That is 795*cos(25). And use that speed in d = vt where d is 100 km to find the time.
 
I quoted it word for word, that is all your given =(

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}...
