Please take a look at that problem

[zinedine_88]

Two springs, spring constants K1 and K2, are attached to a block of mass M on a frictionless table as shown. What will (w) be for the simple harmonic motion of the block if it is kicked?

what should I do... please give me a hint...


the picture is like..

|##$-----@ where$## represents the spring with constant k1
and $$$$ represents the spring with constant k2
@ is the block attached to the springs...


the hint is that I have to isolate the point between the two srpings... I tried but I did not get the answer..

which is

w=sqrt(k1*k2/(k1 + k2)*m)

PLEASE I HAVE A FINAL on tuesday hel me...

If you stretch the block through a distance X by applying a force F, the spring S1 will stretch through X1 and spring S2 will stretch through X2. Since for the spring F = kX, X1 = F/k1 abd X2 = F/k2. Now find the spring constant of combined spring and find the (w).
