I tried many ways to perfomr this problem, but i just cant figure out whether or not Im using the right values.(adsbygoogle = window.adsbygoogle || []).push({});

"A 25 ton truck loses it brakes and reaches the bottom of a hill with a speed of 60 mph.

Fortunately, there is a runaway truck ramp which is inclined at angle of 15 degrees to the horizontal."

Assuming no losses, what distance does the truck travel along the runaway truck ramp? (miles) ?

The KE of the truckjust before it goes up the ramp is 6010000 ft-lb.

What do I need to do to get the distance the truck travel along the ramp? The length of the ramp is 1 mile if that means anything.

Heres a formula Ive used : KE1+PE1+Work=KE2+PE2+Eloss

Im not sure what force i need to use. I would guess the 6010000 I found.
