Re: Physics Quiz 8

Energy in the system = F^2 / 2K
Length when stretched (L3) = L + F/K

Potential energy at L2 = 0.5K*(L2-L)^2

Kinetic energy @L2 = F^2 / 2K - 0.5K*(L2-L)^2

Velocity@L2 = Sqrt(2/M( (F^2 / 2K) - 0.5K*(L2-L)^2 ))
=Sqrt(2K/M( (F/K)^2 - 0.5(L2-L)^2))

I don't know what to do with that.
