Answer:

Coefficient of static friction required = 0.94

Step-by-step explanation:

Coefficient of static friction required
=(v^2)/(gR)

Velocity, v = 120 km/h = 33.33 m/s

g = 9.81 m/s²

R = 120 m

Coefficient of static friction required
=(33.33^2)/(9.81* 120)=0.94

Coefficient of static friction required = 0.94
