richbwfc Posted January 16, 2008 Share Posted January 16, 2008 Hello there. Havent been on here for a while. Hope everyone is well? You will be pleased to hear I have now grown up and am not a silly little boy. But I still expect the piss-taking so... Anyway. I saw this question on another forum. See if any of you lot can do it So, you are on a train. The train is travelling north at a velocity of 50mph. You are in the first class carriage, in which there is an escalator moving in the opposite direction (south) moving at a velocityof 6mph. The escalator is angled at 45 degrees. You, being the messer that you are, are running in the opposite direction on the escalator at a velocity of 8mph. So, what direction are you moving, in relation to the ground, and at what velocity taking all factors into account?

Site Supporter MickyD Posted January 16, 2008 Site Supporter Share Posted January 16, 2008 Oh, the velocity would be 52mph but as the escalator is at 45o. . . hey, hang on, how tall is the train to have an escalator at 45o? Would it get under bridges or tunnels? Link to comment Share on other sites More sharing options...

SatanGreavsie Posted January 16, 2008 Share Posted January 16, 2008 So, you are on a train. The train is travelling north at a velocity of 50mph. Train at 50mph?? Can we stick to questions pertinent to the real world please. eg You've had to get off the train at Northampton due to engineering works at Rugby. The bus to take you onwards to Birmingham is due in 30 minutes, but is reported to be 15 minutes late thanks to the flooding. Assuming the station buffet is a 5 minutes round trip away, how many cans of Stella should you get for the journey to Brum given that the maximum speed of the bus is limited to 50mph, the journey is 80 miles, the diver isn't sure of the best route, and the bogs are closed at the station.

richbwfc Posted January 16, 2008 Author Share Posted January 16, 2008 The train is modelled as a particle so therefore no air-resistance/friction occurs. I take it all these extra questions means no-one can actually do it? Link to comment Share on other sites More sharing options...

Traf Posted January 17, 2008 Share Posted January 17, 2008 If you want a serious answer Rich, you're wasting your time. Work it out for yourself, using this as a clue. If you're on a train travelling 100mph and you jump up in the air, why do you still land on the same spot? Link to comment Share on other sites More sharing options...
