A car without ABS (antilock brake system) was moving at 16.5 m/s when the driver hit the brake to make a sudden stop. The coefficients of static and kinetic friction between the tires and the road are 0.553 and 0.410, respectively.
(a) What was the acceleration of the car during the interval between braking and stopping?

(b) How far did the car travel before it stopped?

  • Physics -

    Vf^2=Vi^2 + 2ad


    how far, use the first equation. use a (acceleration as negative)
