A1000-kg car is slowly picking up speed as it goes around a horizontal curve whose radius is 100 m. the coefficient of static friction between the tires and the road is 0.350. at what speed will the car begin to skid sideways?

18.5 m/s

Explanation:

On a horizontal curve, the frictional force provides the centripetal force that keeps the car in circular motion:

where

is the coefficient of static friction between the tires and the road

m is the mass of the car

g is the gravitational acceleration

v is the speed of the car

r is the radius of the curve

Re-arranging the equation,

And by substituting the data of the problem, we find the speed at which the car begins to skid:

yup its correct its: c) b b
