Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 34.0 m radius?

Respuesta :

Answer:

14.139m/s

Explanation:

For a body moving along a curve on a surface whose coefficient of friction is [tex]\mu[/tex], the maximum velocity v the body can sustain beyond which it would skid off is given by equation (1);

[tex]v=\sqrt{\mu gR}............(1)[/tex]

where g is acceleration due to gravity taken as [tex]9.8m/s^2[/tex] and R is the radius of the curve.

Given;

[tex]\mu=0.6\\R=34m[/tex]

Hence'

[tex]v=\sqrt{0.6*9.8*34} \\v=\sqrt{199.92}\\ v=14.139m/s[/tex]

Answer:

Speed = 14.15 m/s.
