Adriver in a car speeding to the right at 24m/s suddenly hits the brakes and goes into a skid, finally coming to rest. the coefficient of static and kinetic friction between the tires and the road are s = .8 and k = 0.7. how far does the car skid?

42 m

Explanation:

= initial velocity of the car = 24 m/s

= final velocity of the car = 0 m/s

μ = coefficient of kinetic friction = 0.7

g = acceleration due to gravity = 9.8 m/s²

a = acceleration due to kinetic frictional force  = - μg = - (0.7)(9.8) = - 6.86 m/s²

d = distance through which the car skids

Using the kinematics equation

Inserting the values

d = 42 m

coil wire, increase current, put iron inside the coil
