Sorry, the question actually asks for the speed, not the time. x is not necceserally greater than d, although in the question it is. 'x' isn't displacement. I am using T = mg = [λ (x + d)]/l So, for x > d, this is happening: http ://img59.imageshack.us/img59/3192/shm2qa4.jpg Where...

Well it will be soon, what with exams and all... :wink: What I don't understand, is how my statement "if d = x, the motion of the particle would be exactly the same as a spring on a frictionless horizontal surface" could be true. I don't know what you mean by 'equation of motion'. This is...

Thanks, tiny-tim! OK, if I understand both of you correctly, the particle (A level maths student :"]) will act simple-harmonically when " l < OP < l + d + x ", ie motion through 'd' mirrors the motion through 'x' until (x - d) and if d = x, the motion of the particle would be exactly the same...

My first post here! I signed up a few minutes to correct someone... then deleted my post when I realized I was on about something entirely different. Ahem. Anyway, have a look at this diagram: http://img2.freeimagehosting.net/uploads/c8911ecf7e.jpg Particle P is suspended on an...
