## Homework Statement

A car can decelerate at -4.80 m/s2 without skidding when coming to rest on a level road. What would its deceleration be if the road were inclined at 13$$\circ$$ uphill? Assume the same static friction coefficient.

## Homework Equations

Ff=$$\mu$$SFN

## The Attempt at a Solution

Well I cant find anyway to even start can someone head me in the right direction?

I think I got some of it:
$$\Sigma$$F=ma
Ff+FN-Fg-Fp=ma
Ff+FN-ma-Fp=ma
+ma both sides and +Fp
Ff+FN=2ma+Fp
$$\mu$$sFN+FN=2ma+Fp

Now I'm wondering if there is actually Fp for the car or not (force of push). Would there still be a pushing force of the car when decelerating?
Stuck there now :\
