acceleration. linear motion. i'm stuck!!! 1. The problem statement, all variables and given/known data a train moves at a velocity of 60 m s-1 and stops after a distance of 600m. what is its deceleration? 2. Relevant equations v=s/t 3. The attempt at a solution this is my working: u= 0 m s-1 v= 60 m s-1 s= 600 m v=s/t 60=600/t t=10 s ...and i'm stuck here. please help!!!
