Ok maybe I am going to be wrong to put it this way but seems that distance traveled is unimportant here to the original author..what if he just wants to know Time from a to b at with that given acceleration and the made up or not slope to add to the fun...and could care less how far the car...
Guess the author of this problem expects for the "made up or not slope" of 6.4% to be considered...just go with it..he didnt include friction nor mass throughout the slope so assume the given acceleration is "average" as stated from Zero to 230mph at finish all throughout the incline...you guys...
Could we assume that in this case 203mph is reached at the moment the car crosses the finish line and consider it Vf..? Could the time from "a" to "b" be determined then...?
I think u are really misinterpreting the picture.
Pikes Peak its a real race course..and including its 156 turns its actually a total of 12.42m from start to finish. What its asked here is to eliminate the curves..GET OFF THE ACTUAL COURSE and pretend to drive straight through from start to...
Unsolvable..?.Why so salty?..can u work with what's presented and not assume anything like oxigen levels and stuff like that but the given the assumed acceleration?
how can one figure remaining distance on the given 12.42miles if its all turns and curves regardles of how many miles the car has traveled on a straight line?.its the 12.42m just there to mislead people on this calculation?
Looks to me that start (a) to finish (b) are completely uphill and the speed is 0 at (a) to 203mph at (b)...yes 12.42 miles are the total real course mileage including 156 turns...the mileage to be ran its assumed to be shorter
Lol...I understand. I have the same problem as the OP is trying to solve that's all. But i don't see Nate chipping in so I'm assuming he is just reading the posts..😁
Im not sure if this is the formula i should use to find the true acceleration
a=g*SIN(tetha)...would that be a negative? as in...
