a driver sees a horse on the road and applies the brakes so hard that they lock and the car skids to a stop in 24 m. the road is level and the coefficient of kinetic friction between the tires and the road is 0.7. How fast was the car going when the brakes were applied?

    Vf^2=Vi^2+2ad
    but a=force/mass=mu*mg/m=mu*g
    solve for vi
