## Homework Statement

On Mountain roads, ramps of gravel are constructed to allow trucks that have lost their brakes to come to a stop. Suppose a 15,000kg truck hits one of these ramps at 35m/s. The incline of the ramp is 6 degrees and the coeffiecent of friction is 0.40.

By using work and energy it is asked to find the distance the truck travels along a ramp.

## Homework Equations

U=m*g*h

K= 1/2 m*v2

W=F*d

## The Attempt at a Solution

I calculated K to be -9187500 and U to be 147150*h

W= ΔK + ΔU

Then tired to use W=F*d cos6

But got stuck with that height.

I can't use trig fuctions to find my h because the distance is what im trying to find....
