A driver in a car speeding to the right at 24m/s suddenly hits the brakes and goes into a skid, finally coming to rest. The coef
irina [24]

Answer:

42 m

Explanation:

v_{o} = initial velocity of the car = 24 m/s

v_{f} = 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

v_{f}^{2} = v_{o}^{2} + 2 a d

Inserting the values

0^{2} = 24^{2} + 2 (- 6.86) d

d = 42 m
