I tried many ways to perfomr this problem, but i just can't figure out whether or not I am using the right values.
"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 truck just 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 I've used : KE1+PE1+Work=KE2+PE2+Eloss
