hello(adsbygoogle = window.adsbygoogle || []).push({});

I'm having some trouble with the following problem:

train B leaves point A at 8am to point B located 30 km straight a head.

the train has constant acceleration a=0.05 m/sec^2

now train B leaves point B 5 minutes before train A gets there,what is the acceleration of train B in order for the trains to meet with the same velocity?

(i.e will not collide)

I computed the speed of train A 5 min before it arrived to point B.

I know it's acceleration,but it seems I dont have enough information to solve the problem,I have 2 unknowns: train B's acceleration and the location they meet...but I have only one equation.

can someone please help me.
