Hey again, I've come across yet another problem and this one doesn't even compare to the last one (I'm an idiot, haha). Anyways here it goes:
A sports car, Fiasco I, can accelerate to 120 mph in 30 seconds. Its max braking rate cannot exceed 0.7g. What is the minimum time required to go...
it took the bird 30 minutes to get to the collision point BUT the bird flies to the second train going -30km/hr and meets the second train at the 40km mark in 40 minutes...that's what I got and then flies back and meets the first train at the 27.5km mark in 15 minutes.
and an hour for the...
I solved up to when the trains are 5 miles apart...I drew the problem out and used ratios but I know there has to be a more direct way. LoL, I'm sorry I'm a complete blank slate when it comes to this (calc teacher sucked and my last math before that was 3 years ago).
with t=0, the entire equation would be 0? I tried that but the time is what throws me over because I don't know what time they will meet (both the train and bird).
Still don't get it because I mean both the train and the bird are moving so how would I make 2 separate equations correlate? I'm assuming since you said a=0 and that I need to find the time that I am using v^2=vi^2+2a(x-xi) equation. Yet, I don't have the distance unless it is the 60km but that...
Basic Physics...??
Hey Everyone, I just started the course and the first problem I come to, so very confused me! I don't need an answer just a basic response on exactly HOW I can approach this problem because I am just totally blown away by it .
Two trains, each having a speed of 30...
