My first post :D
I have an incline of angle (θ) to the horizontal, and a chain of length (l) of a uniform mass (m), I place the chain so that one end is at the bottom of the incline, the entire system is frictionless.
I need to find what the velocity is as the last end leaves the incline, and how long this took.
Since the system is frictionless then am i right in assuming the the length (let call it x) that has already left the incline no longer has any significant influence on the system with regards to finding the velocity?
If so then can i simple sett it up as
0,5mv^2=mglsin(θ)
and get
v=√2glsin(θ)
and then find the time to be
t=[√(2glsin(θ))]/[gsin(θ)]
but that just seems to simple...
