a train moves at a velocity of 60 m s

^{-1}and stops after a distance of 600m. what is its deceleration?

**2. Homework 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!!!
