Truck - 2 hills - friction

[Jhero]

Can I get some help on this problem?

A truck with mass m has a brake failure while going down an icy mountain road of constant downward slope angle theta. Initially the truck is moving downhill at speed Vnot. After careening downhill a distance L (hypotenuse) with negligible friction, the truck driver steers the runaway vehicle onto a runaway truck ramp of constant upward slope angle B. The truck ramp has a soft sand surface for which the coefficient of rolling friction is MUr. What is the distance that the truck moves up the ramp before coming to a halt? Use energy methods.

I have no clue where to start :confused:
