A car traveling at 60mi/h (88ft/s) skids 176 ft after its breaks are suddenly applied. Under the assumption that the braking system provides constant deceleration, what is that deceleration? For how long does the skid continue?

First this problem is suppose to be at the Physics section.

Anyway.

First, identify all the known variables. Then identify all the five kinematics equations. Now plug the known variables into one of the kinematic equation.

One thing you have to make sure is that the direction of the acceleration is negative.

D=T(vf+vi)/2 can be used to find time.

You should be able to find the equation for for acceleration.

hope this helps

Try v^2 = u^2 + 2ad
