Here, s = V2/2gf.
Where V in m/s and F = 0.35,
Answer is 10.11.
Where V in m/s and F = 0.35,

F = u^2/29*L
L = 8.33*2/19*0.2 = 11.96~12m.
Assume f = .20.
L = 8.33*2/19*0.2 = 11.96~12m.
Assume f = .20.

Option A is correct. s=((v*v)/(2gf)).
S = 10.11.
S = 10.11.

Stopping dist.= (0.2 *vb+6).
= (0.2*30+6) = 12.
= (0.2*30+6) = 12.

8.33^2/2 * .30 * 9.81,
= 11.78~~12.
= 11.78~~12.
