AI Thread Summary
Two trains traveling towards each other at 44.3 km/h are initially 132.9 km apart. To determine the time until they collide, the total speed of both trains is combined, resulting in a collision time of 1.5 hours. The bird, flying at 177.2 km/h, continuously travels back and forth between the two trains during this time. By multiplying the bird's speed by the time until collision, the total distance the bird travels is calculated to be 265.8 km. The discussion highlights the importance of understanding relative motion and speed in solving such problems.

2 trains have the speed 44.3 km/h, are headed each other on the same straight track. A bird that flies 177.2 km/h flies from the front of one train when they are 132.9 km apart and heads directly other train. On reaching the other train it flies directly back to the first train, and so forth.

what is the total distance the bird travels?

So i figure that I have to use pythagorian theorem. One of the legs is 132.9km but I don't know how to find the other leg. Thanks.

There are no triangles involved here, so Pythagoras isn't necessary.

There's a hard way and an easy way to do this problem. I'll let you think about it some more.
 
Crap, ok i disreguarded the "same" straight track. Ok so the are going head to head! But is there an equation to find the time when two objects are approaching each other? I don't know many equations, we haven't gone over any in class.
 
ok i thought i figured it out at 170.1km, but it says that is wrong. What did i do wrong?
 
First we want to find the time the two trains will collide. So \frac{132.9 km}{44.3 \frac{km}{h}+ 44.3\frac{km}{h}} = \frac{3}{2} [/itex] hours. So multiply the eagles speed by this. Remember distance divided by velocity gives you time according to d = rt

I'm curious as to what kind of bird this is that flies at 177.2 km/h.

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}...
