A.Rose:
Hello
I just need some help with this question - a little confused with what is happening...what is the stopping length?
Thank you!
Bri MT:
Hey!
It's asking you how much distance the truck will cover before coming to a stop.
A.Rose:
Oh ok, so its how much distance the truck will cover on the ramp before stopping...? Just need another clue. I'm not given its mass or anything just initial velocity and an angle. Usually, inclined plane Q's I need the parallel component...?

Yeah it's how much distance the truck would cover on the ramp before stopping.
This isn't a standard inclined planes question, it's about using the constant acceleration formulas (keeping in mind that unlike weight which would need you to know mass, acceleration due to gravity is constant on the surface of Earth - combine this with knowing the angle).
You've been given initial velocity & you set final velocity equal to 0 (because its stopping distance)
A.Rose:
Oh, of course, thank you!
