Friction and Acceleration in Automobiles

[Marioqwe]

Homework Statement

Determine the maximum theoretical speed that an automobile starting from rest can reach after traveling 400 m. assume that the coefficient of static friction is .80 between the tires and the pavement and that (a) the automobile has front wheel drive and the front wheels support 62% of the automobile's weight, (b) the automobile has rear-wheel drive and the rear wheels support 43% of the automobile's weight.

Homework Equations

F(friction) = (coeff. friction)(normal force)

The Attempt at a Solution

My question is that why they give me static friction instead of kinetic friction.
((Does that mean that kinetic friction only applies when the acceleration is not constant and/or zero?))-->NVM this

Because your truck started from rest, you need to know how much net force it needs in order for it start moving which must include overcoming friction.
