Hey!
I have a question about the following problem:
A train is traveling at 100 m/s. The engineer applies the breaks because he sees the Batmobile stuck on the tracks ahead. The breaks cause an acceleration of -2.2 m/s^2. The engineer applies the breaks when the train is 960 m from the Batmobile. How long does it take the train to reach the Batmobile?
I thought I would use the linear motion equation of:
X = Xo + Vo(t) + 1/2at^2
But I became confused because I didn't know what to do about the distance "X" Is 960 the initial or final distance? A hint would be greatly appreciated.
Thanks
