Question

The driver of a 1900 kg car (including passengers) traveling at 26.0 m/sm/s slams on the brakes, locking the wheels on the dry pavement. The coefficient of kinetic friction between rubber and dry concrete is typically 0.650.

a)Use the work-energy principle to calculate how far the car will travel before stopping.  s=

B)How far would the car travel if it were going twice as fast?

c)What happened to the car's original kinetic energy?
