kratos009:
Oh right thanks tyserius. But if you know where to get past papers before 2002 for Chemistry i would really appreciate it cause my MCQ for chem is on the 20th of November so i got loads of time to study for it...thanks for the question. :D

The Question is ( By the way, it's subjective but worth a try ;D ):
A train driver spots another train 80m ahead, moving away from his train. If the driver's train is moving at a speed of 100km/h and the other train is travelling with a speed of 50km/h, what deceleration should the driver apply to his train in order to avoid a collision?
Have fun :)

Nope you can't do that just that way 'cause both trains are moving just that the driver is having his train faster than the other and if he keeps up the speed he'll definitely collide. So, think about it? :P
@falafail : Haha :P It's not easy, it involves some inequalities :P
