Steps
1) use equation of motion
v^2 = u^2 + 2*a*s , to get accelaration
2 ) direction of retardation accelaration is always opposite to the direction of motion
3) Again use equation of step 1 to get total distance covered
4) Again use ist step equation to get velocity at a distance d/2
Now use equation v= u + a* t
to get time elapsed .
