Question

Consider a circular leveled road of
radius 10 m having coefficient of static
friction 0.81. Three cars (A, B and C) are
travelling with speed 7 m s', 8 m s and
10 ms respectively. Which car will skid
when it moves in the circular level road?
(g =10 m )
Solution
From the safe turn condition the speed​

Answer 1

Answer:

Three cars (A, B and C ) are travelling with speed 7 ms-1, 8 m s -1 and 10 ... The cars A and B will have safe turns. ... Hence, the car C will ...

Answer 2

Answer:

Cars A & B will safely turn while Car C fails (Will skid)

Explanation:

          radius  =  10m  

        μs       =   0.81

        Va       =  7 m/s

        Vb       =  8 m/s

        Vc       =  10 m/s

For safe turn,

                V   ≤    √μs * r * g

                V   ≤    √0.81 * 10 * 10

                Vsafe   ≤    9 m/s

Va < Vsafe

Vb < Vsafe

Vc > Vsafe  (will skid)
