How Do You Calculate Stopping Distance on a Slope?

[cec87]

Problem:
A car is traveling up a 15 degree slope at a speed of 35.0 m/s when the driver slams on the brakes and skids to a halt. The coefficient of kinetic friction between the tires and road is 0.800. Find the cars acceleration and the stopping distance.

I found the acceleration and was trying to the find the stopping distance using x=xo + voxt+ axt^2/2. I don't know if this is the right approach.

This is how I would solve for the stopping distance. I think you are on the right track. Continue working and see if you get the right answer. If not, then we are here.

I suppose you could use v^2=u^2+2as
