Dear Ram, so here it goes-
Speed of car on the road , v = 36km/h
= >36 × 5/18 = 10m/s
coefficient of friction between tires and road =0.5
Let radius of car is r
use formula, v=squareroot(u*r*g)
where g is acceleration due to gravity and u is coefficient of friction.
10×10 = 0.5 × r × 10 [taken g = 10m/s² ]
r = 20m
hence, minimum turning radius of car is 20m.
All the best
Hope this helps
