Re: Physics Help here! Stuck somewhere?? Ask here!

In case you haven't noticed, the motion of plank is also simple harmonic.
So period is proportional to mass. mass decreases period decreases.
amplitude increases because pull has decreased.

problem in A2 Physics 2013 p-52
question- 1
pllease help me out

[papajohn]

explanations ate available at http://physics-ref.blogspot.com/2014/05/physics-9702-notes-worked-solutions-for.html
(below the links for the worked solutions)

+ arvin vinz it would be better that you don't link to papers when commenting there. That's why your comment was not published

Great work dude..
