A train starts from a station A, and moves with uniform acceleration. In 1.5 minutes it passes a station B, and 1 minute later another station C. If the distance between B and C is 1,200 yards, find (a) the acceleration of the train, (b) the distance between A and B.
I do not know how to find the acceleration!
The formulae are: v=u+at; s=ut+1/2at^2; v^2=u^2+2as;
where: v= final velocity, in ft/s,
u= initial velocity, in ft/s,
a= acceleration, in ft/s/s,
t= time in seconds.
Thanks in advance.
