Homework Statement
A 1400-kg automobile is driven down a 4 degree incline at a speed of 88 km/h when the brakes are applied, causing a total braking force of 7500 Newtons to be applied to the automobile. determine the distance traveled by the automobile before it comes to a stop.
Homework Equations
(1/2)*m*v1^2 + total work = (1/2)*m*v2^2
The Attempt at a Solution
so far I have the equation (1/2)*m*v1^2 + total work = (1/2)*m*v2^2
so i have the work of weight which is -1400cos4, the work of friction which is -7500 and initial velocity of 88 km/h. I don't really know how to put this together. please help
