Folding Ramp Has one of your youngin's ever found something "of yours" and took it to school for show & tell?
My daughter found, and took to school a velcro'd blind fold that said "THE LIBERATOR" on it. It was part of the $100 bonus package that shipped with the ramp/wedge combo. She was wearing and showing it off all day in school and on the bus. That night, she wore it to bed, and was discovered.
Should I have shipped her hot teach a ramp/wedge combo pack as a friendly gesture?
POLL: Ship it to the teacher! >or< Ship it to me!
I think I need to study the Urban Dictionary some more.....

FOUND: vi=sqrt(-2kd/m)
(b)The box now slides frictionlessly up a ramp of length L, inclined at angle θ above the horizontal. What is Vf at the top of the ramp? Answer with the variables m, k, d, L, and θ.
(c)The box then continues across a rough section of length s of horizontal floor that has friction coefficient μ. What is Vf? Use variables: m,k,d,L, θ, and μ.
(d) Nest you are sitting on the frictionless floor with your back to a wall. The box is coming straight at you. You extend your arms. Your arms fold a distance x while you apply a constant force to the box, stopping the box. Magnitude of constant force? Use variables: m,k,d,L,θ, μ and x
Any help would be appreciated. I got stuck after part A and I'm unsure what formula to use, although I can see that the Vf from one part is the Vi for the following part.
Without part A, I'm not sure what variables signify.
But for part b, its best to use conservation of energy:
½mVi² = ½mVf² + mgh
which simplifies to:
Vi² = Vf²+2gh
Vf² = Vi²-2gh
Vf² = (-2kd/m)-2g(Lsinθ)
For part c, first find a:
F = ma = -μmg
a = -μg
Then use motion equation:
Vf² = Vi²+2as
Vf² = (-2kd/m)-2g(Lsinθ)-2μgs
