Q : A train of mass 8.0 [tex]\times[/tex] 10[tex]^{}6[/tex] kg, travelling at a speed of 30 m s[tex]^{}-1[/tex], brakes and comes to rest with a constant deceleration in 25s.

(a) Calculate the frictional force acting on the train while decelerating.

(b) Calculate the stopping distance of the train.

2. Relevant equations

I have no idea which equations to use...

3. The attempt at a solution

Well... first i found the net force which is zero because it is contant negative acceleration. I then attempted a diagram. I dont know what do do next.
