Then we will calculate the other unknown values in a normal way without the third stage of the addition of the two distances since Xo is 0. i think i understand those types of exercises now.
I didn't really understand wdym by a former F1 champion, but if he has a 0 reaction time, then X1 will be igual to 0 since there is no time of reaction.
Thank you so much for everyone that helped me and gives me the advices about the right strategy to do and the solution, i really appreciate that from every one of you, and i still have some other exercises that i 'm confused about, i will try my best to do them, if i needed help, i will come...
In the second step, do i have to remove it and replace it to zero ? so in this case, does that mean that the Xo after the acceleration is 0, because i though it's was 5m (if like we talked in general). Is this the wrong thing about 5m ?
the second part is correct, I'm confused about the 5m thing, what is wrong about it? since the acceleration is not included, the only way to do it is by using the basic method that we know: V = d/t, do i have to use an another method? Or i have choose the wrong numbers ?
Okay so, the first thing that i did in this picture i think it's correct, the second one maybe wrong, if we suppose that the Xo = 0'75 m / Vo = 120km/h = 33'3 m/s / a = -6m/s² (since the velocity is not augmented). so we need to search for two things: the time and the final distance. please...
