Question

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?

Answer 1

Answer:

14.139m/s

Explanation:

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

$v=\sqrt{\mu gR}............(1)$

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

Given;

$\mu=0.6\\R=34m$

Hence'

$v=\sqrt{0.6*9.8*34} \\v=\sqrt{199.92}\\ v=14.139m/s$
