v2 = vo2 + 2as

v = final velocity = 0 .. remove from equation.

vo = initial velocity = 32 m/s.

a = acceleration ( deceleration in this case ).

s = distance. That is, the total distance including the skid.

Rearrange to solve for s:

2as = -vo2

s1 = -(vo2/2a)

s1 = -{32^2/2(-8)}

s1 = 64m on dry road.

s2 = {32^2/2(-3)}

s2 = 170.7m On ice.

Δs = s2 - s1

Δs = 170.7 - 64

Δs = 106.7m
