Homework Statement
The hand in (Figure 1) (a) holds a vertical block-spring system so that the spring is compressed. When the hand let's go, the block, of mass m, descends a distance d in a time interval Δt before reversing direction in
(Figure 1) (b). Once the system comes to rest, the block is removed, a block of mass 2m is hung in its place, and the experiment is repeated.
to what maximum distance does the block descend?
Express your answer in terms of π, acceleration due to gravity g, some or all of the variables m, d, and Δt.
Homework Equations
k(xeq-x0)=mg
the basics for shm
x=Asin(ωt+Φ)...a=Aω^2sin(ωt+Φ)
The Attempt at a Solution
k(xeq-x0)=mg
k(xeq2-x0)=2mg
...xeq2-x0=2(xeq-x0)
so I know xeq for 2m will be twice as far from x0 of spring as for m, but x0 is not given
and I thought I just calculated 2m would drop twice as far past xeq than m (but I can't seem to find those so they could be wrong)
I havn't got my head around this problem yet but its turning into a monster and
I'm running out of time so any guidance would be apreciated
